  2. The slightly cheaper member of the premium laptop family is still as elegant. Samsung has really impressed me with its laptop game lately, delivering super thin and premium machines like the Galaxy Book Flex and Ion, as well as the Snapdragon-powered Book S. But those devices cost upwards of $999, which cuts the budget-conscious user out of Samsung's reach. For those who would like something just a little cheaper, though, the company announced a new Galaxy Book last week called the Flex Alpha. That rings in at $830, compared to the roughly $1,100 that the Flex and Ion are expected to cost. I was concerned that to drop the few hundred dollars, Samsung would have had to sacrifice build quality and deliver a machine that felt cheaper. But once I picked up the Flex Alpha here at CES 2020, I was relieved. The laptop is just as premium to the touch as its costlier siblings, with a similarly sturdy, thin and light frame. It has the same sumptuous QLED screen, running at full HD, and can also hit an impressive 600 nits of brightness in a "Outdoor Mode" you can activate when needed. Thanks to the energy-saving benefits of QLEDs, the Flex Alpha should offer plenty of battery life, though it has a smaller 54Whr battery compared to the 69.7Whr cells in the more-expensive pair. The 2.6-pound Flex Alpha isn't the slimmest or lightest laptop around, but it certainly seems like one of the most attractive for its price. I'm glad Samsung didn't have to sacrifice too much -- you'll still get the same fingerprint sensor on the keyboard for convenient logins, as well as two USB-A 3.0 sockets, one USB C port, a microSD card reader, an HDMI slot and a headphone jack. The main tradeoffs Samsung had to make here in addition to the smaller battery, were limiting the graphics card and storage choices. You'll only get integrated Intel UHD graphics, instead of having the option to upgrade to more powerful Iris Pro or NVIDIA MX 250 cards. Still, you can get the Flex Alpha with tenth-generation Intel Core processors, which is reasonable for the price. The new laptop will be available by the first half of the year, so if you've been looking for a stylish QLED laptop under $900, this might be worth your time. Source
  3. This post will introduce a simple udev rule and ~$20 in USB hardware that effectively implements a kill cord Dead Man Switch to trigger your machine to self-destruct in the event that you’re kicked out of the helm position. Let's consider a scenario: You're at a public location (let's say a cafe) while necessarily authenticated into some super important service (let's say online banking). But what if–after you've carefully authenticated–someone snatch-and-runs with your laptop? Maybe you can call your bank to freeze your accounts before they've done significant financial harm. Maybe you can't. Or maybe your laptop was connected to your work VPN. In less than 60 seconds and with the help of a rubber ducky, the thief could literally cause millions of dollars in damages to your organization. Surely there must be some solution to trigger your computer to lock, shutdown, or self-destruct when it’s physically separated from you! There is: I call it BusKill. Surprisingly, I couldn’t find a low-tech solution that implements a laptop kill cord, so I decided to build one myself for ~$20 and a simple udev rule. Demo Here’s a quick video demo showing BusKill triggering a kill signal when the magnetic breakaway is tripped. https://tech.michaelaltfield.net/wp-content/uploads/sites/5/2019/12/busKillDemo.webm?_=1 Hardware The key to BusKill is using a cable that will trigger a udev remove action when your laptop is stolen. You could just have a usb thumb drive on a retractable lanyard (think RFID badges or DoD Common Access Cards), but what if that thin retractable cord just snaps–leaving the USB drive snugly in-place in the laptop? My $20 in BusKill hardware (USB-A) A better solution is to attach the USB device as close & snugly connected to your body as possible and run a data cable all the way to the computer. This can further be improved using a break-away magnet connector as close to the machine as possible. For example, the following items are sufficient to build this USB kill cord: A cheap $4 USB drive with durable keyring hole A small & strong carabiner keyring for attaching the above drive to your belt loop (I like this $6 one because it’s small, well-made, and has a clever locking mechanism) A $7 USB magnetic breakaway adapter to plug into the computer’s USB-A port And finally, a $3 1-meter USB extension cable to connect them It’s 2020, and a lot of laptops no longer have USB-A ports on them. If you only have a USB-C, you can either go hybrid by adding this: $9 USB-C to USB-A converter Or go full USB-C with: A cheap $9 USB-C drive A $24 USB-C magnetic breakaway adapter And a $13 1-meter USB-C extension cable Software To set this up, we need to add a new udev rule file to /etc/udev/rules.d/. Here’s a simple rule that will trigger xscreensaver to lock the screen every time any USB drive is removed: cat << EOF | sudo tee /etc/udev/rules.d/busKill.rules ACTION=="remove", SUBSYSTEM=="usb", RUN+="DISPLAY=:0 xscreensaver-command -lock" EOF sudo udevadm control --reload But that rule may be a bit too broad. If you want to have a specific brand of USB drive trigger the lockscreen, first we need to do some debugging to find some properties that are triggered by your BusKill-specific usb drive when it’s ejected. To get those, follow this procedure Step 1: Insert your USB drive Step 2: Run udevadm monitor --environment --udev Step 3: Remove your USB drive Check the output of the udevadm command. You should see a bunch of potentially uniquely identifiable properties about your drive, such as the manufacturer, model, filesystem uuid, etc. For example, let’s say we see the following line indicating that the ID_MODEL property of your USB drive is Micromax_A74. $ udevadm monitor --environment --udev ... ACTION=remove ... ID_MODEL="Micromax_A74" ... SUBSYSTEM=usb ... Then we can update the udev rule to be: cat << EOF | sudo tee /etc/udev/rules.d/busKill.rules ACTION=="remove", SUBSYSTEM=="usb", ENV{ID_MODEL}=="Micromax_A74", RUN+="DISPLAY=:0 xscreensaver-command -lock" EOF sudo udevadm control --reload And, of course–depending on the risk model–you may want the kill signal to actually shut down your machine: cat << EOF | sudo tee /etc/udev/rules.d/busKill.rules ACTION=="remove", SUBSYSTEM=="usb", ENV{ID_MODEL}=="Micromax_A74", RUN+="shutdown -h now" EOF sudo udevadm control --reload Conclusion We do what we can to increase our OpSec when using our laptop in public–such as using a good VPN provider, 2FA, and password database auto-fill to prevent network or shoulder-based eavesdropping. But even then, there’s always a risk that someone could just steal your laptop after you’ve authenticated! As of yesterday, that’s a hard attack to defend against. As of today, we have BusKill. The BusKill solution described in this article can trigger your laptop to self-destruct if it’s physically separated from you. Because the data cable runs all-the-way from your body to the laptop, cutting the cable will still result in BusKill triggering. BusKill is simple. There is no need for anything to actually be stored on the USB drive. And if the USB drive suddenly failed, BusKill would still be triggered. If an attacker quickly inserted a clone of your USB drive before or after stealing your laptop, BusKill would still be triggered. And because it’s just a cable, there’s no risks of the attacker using some complex vector of attack over bluetooth, RFID, etc. Source

    What keyboard layout have?

    I tried to install an operating system on a friend's laptop and I can't find out what language the keyboard has Can someone help me?
  5. My laptop just hung without any error and I had to restart by long pressing the power button. There was no indication of what caused the issue. I was simply browsing in my firefox to purchase some steam games and suddenly mouse and keyboard all stopped. Is there a way to figure out the exact cause for Windows 10 hanging issue? Is there any log of error somewhere even though it didn't display any error, neither before nor after restart. My laptop is still in warranty period so if there is any hardware issue, I can get it fixed/replaced. Any Idea.. Thanks.
  6. Hello experts, I have a Dell Latitude 3490 Laptop. It comes with Windows 10 Pro Pre-installed. Around 3 months before I did a Windows Update after that I have witnessed a "Yellow" "Lock" Icon present in the Drive volumes, I thought the Windows is protecting the drives, but i didn't know that it was "BitLocker Encryption" at that time. Three days before i had given my laptop to the Dell Service center as it couldn't power on. They have replaced the Motherboard. Now Windows is asking for BicLocker Recover Key which i don't have, The Laptop HDD is 1TB with 3 partitions, c = 150GB, d = 390GB, e = 390GB all three are encrypted with BitLocker. Note: I never enabled the BitLocker Encryption by myself so I don't have the password / Recovery Keys. Any help would be appreciated Thanks ppu
  7. Any laptop or PC can get Wi-Fi 6 with this single upgrade One small component, one huge difference (Image credit: Intel) The new Wi-Fi 6 standard is here in a pre-release form, replacing the older 802.11ac Wi-Fi found on many recent laptops, desktops, and mobile devices with 802.11ax. But, just because the standard is available for manufacturers doesn't mean devices are getting hardware to support it. It's still new, and even some of the best laptops come without it. But, we've got good news: In many cases, you can add Wi-Fi 6 to your device after you've bought it. How you get Wi-Fi 6 support on your device will depend on the type of device you have. Right now, there are few Wi-Fi 6 modules, and support for AMD systems doesn't appear available just yet. But, if you have a device powered by a 64-bit Intel processor, you can likely make the upgrade. Intel and Killer Networking have cards available, and more options will surely be coming in time. If you have a desktop computer, you can use PCIe connections to add in networking cards, while laptops can use an M.2 slot to fit in the necessary module. We'll go into a bit more detail below. Adding Wi-Fi 6 to a desktop The currently available Wi-Fi 6 modules from Killer Networking and Intel are M.2 cards targeted at laptops, and they won't work in desktop M.2 slots as is. But, that doesn't stop them from working in desktops. You can add in one of these cards by using a PCIe adapter like this one. The M.2 card will slot into the converter, and then the converter will go into an open PCIe slot on your desktop's motherboard. The converter should also provide antennae that connect to small slots on the Wi-Fi 6 module. Once that's slotted into your computer, a quick driver installation will have you up and running on Wi-Fi 6. Adding Wi-Fi 6 to a laptop Laptops are becoming less and less upgradeable, with manufacturers soldering on components and sealing up cases. But, that doesn't mean you can't make this upgrade happen. All but the thinnest laptops and 2-in-1 tablets, like the Surface Pro X, tend to still have some level of access to the internals. And, even if components like RAM are getting soldered onto motherboards, networking adapters can still often be found as add-in cards. If you can open up your laptop (it may take a specialized toolkit), there's a good chance you'll be able to spot the small M.2 module currently powering your device's Wi-Fi and Bluetooth connections. You'll simply unscrew the screw holding the Wi-Fi module in place, and unplug the antenna wires connected to your existing Wi-Fi module. Then, you'll just do the process in reverse to install your new Wi-Fi module. Future solutions may get even easier While the current processes for upgrading are simple, in the near future, it's likely even simpler solutions will come out. We'd expect PCIe cards with the Wi-Fi module built in to make upgrading desktop Wi-Fi much easier. And, we wouldn't be surprised to eventually see Wi-Fi 6 USB dongles that add the new connectivity in a simple, plug-and-play device. So, if you're on the market for a new computer and can't wait for models pre-fitted with Wi-Fi 6 support, you take some comfort knowing that simple upgrade solutions are available. You shouldn't need to upgrade your whole machine just to get a faster, more stable Wi-Fi connection. You will need to get a new Wi-Fi 6 router, like the Asus ZenWiFi mesh router, though.

  8. How much higher could proposed tariffs against China push laptop prices? A new report claims that the Trump administration's latest tariff proposal on goods imported from China could raise prices on new laptops by 17 percent in the U.S. On average the report finds that a new laptop would cost $120 more if the tariffs go into effect. A new report has attempted to quantify just how much proposed tariffs against Chinese imported goods could raise prices on electronic devices, with the results concluding that you could wind up paying an additional $100 or more on your next laptop. The report was commissioned by the Consumer Technology Association, which obviously has a vested interest in how the Trump administration's proposal (tariffs up to 25 percent that would affect many tech items) would impact its members' bottom lines. Nonetheless, its central premise -- that phones, laptops, drones, and video game consoles would face price increases due to the proposed tariffs -- doesn't require much of a stretch of the imagination to envision, given how many of these products either come from China or are built with Chinese-sourced components. One notable finding from the report is that prices for laptops would likely increase across the board, not just for systems directly imported from China. While those notebooks would see the biggest increase -- an estimated 21-percent jump in the price for Chinese imported laptops and tablets -- the report believes that prices for all models would rise 19 percent. This is a bit more extreme than the report's estimates for cell phones, where it thinks Chinese import prices would increase 22 percent, but overall price would "only" rise 14 percent. The report calculates that the price of an average laptop would rise roughly $120 if the proposed tariffs were enacted, pushing the average laptop cost to over $600 for U.S. consumers. As a result of the tariffs, laptop and tablet purchases would decline by 35 percent, according to the report. Manufacturing in Vietnam, Taiwan, and Mexico would be the biggest beneficiary of what would be a major salvo in the U.S.-China trade war, and in fact the Taiwanese tech industry is apparently already feeling the effects of the proposed tariffs. The accuracy of the report's findings could be put to the test when and if the administration goes through with the tariffs, but one of its conclusions would still seem indisputable: Despite the tariffs, China would remain the largest importer of laptops and tablets into the U.S., commanding 80 percent of the market. The Chinese economy would definitely be hurt by the proposed tariffs, but it seems like the wallets of American consumers looking to buy a new laptop could be hurt just as much. Source
  9. Tired of Windows, Mac OS X, and other Operating Systems paid up gradation and support? Do you feel like trying out something new? Or perhaps you want to test the cutting edge in operating system design or find out what the platform of the future is going to be. Or you may simply want to try a system that your friends are using to see whether you can use it on your computer. There are plenty of operating systems available and introducing new OS day by day with so many features and fast processing capability. This page lists a variety of free operating systems available that you can download and install on your computer. Many of the systems are also open source so you can also tinker with the system, find out how it works, and learn from it. Here is the list of best 8 Free Light Weight Antivirus that can save Computer Memory and CPU Power. Related: 7 Best Portable Linux Distro to Boot and Run from USB Are you searching for a lightweight operating system for a netbook? Here is a list of the free lightweight operating system for old laptops that can operate without using much hardware resources and probably boot from the USB itself. Ubuntu Most Linux netbook operating systems seem to be based on this one, so it’s worth starting with Ubuntu. Ubuntu is an operating system built by a worldwide team of expert developers. This fast operating system contains all the applications you need: a web browser, office suite, media apps, instant messaging and much more. Ubuntu is an open-source alternative to Windows and Office that can speed up Netbook. This operating system for an old laptop wasn’t precisely designed from the ground up. Ubuntu is the Linux distro based on the Debian architecture. This ideal OS for old laptop comes with most of the built-in Ubuntu apps (Firefox, Open Office, F-Spot, LibreOffice, Firefox, Thunderbird, Transmission, etc.) that makes this setup different is the compatibility with computer hardware. The GUI is tailor-made to take advantage of the limited real estate laptop screens feature. The Ubuntu platform comes in two forms – LTS(Long Term Support) and non-LTS. The last stable LTS version is 16.04, and the non-LTS is the 17.04. The naming is done with respect to the year(16) and month(04) of the release. Most noteworthy is that this will be the final versions with the Unity-based desktop as the newer releases will switch back to the GNOME-based desktop. Furthermore, as Ubuntu has been the most popular Linux Distribution, it has an excellent hardware compatibility, and the users need not install additional drivers. The software is downloadable from the official Ubuntu Software Center.

Linux Lite Linux lite just as the name suggests was introduced for the systems with lower end hardware. This Linux Lite is a straightforward lite operating system that can benefit especially the news users who have limited knowledge of the Linux operating system as a whole. This Linux operating system is a right combination of programs, tools, desktop, and functionality. The Netbook Linux Lite is based on the Ubuntu distribution and presents a simple interface. As such it is quite stable and has update support for up to five years. The Linux distribution is fully functional right after installation, and the users need not worry about driver issues. As far as best lightweight operating systems are concerned, Linux Lite is right up there on the top. Download Link: Linux Lite Fedora Fedora is the second most popular Linux-based operating system as of early 2010, after Ubuntu. Fedora is an RPM-based, general purpose operating system built on top of the Linux kernel, developed by the community-supported Fedora Project and sponsored by Red Hat. One of Fedora’s primary objectives is not only to contain software distributed under a free and open source license but also to be on the leading edge of such technologies. Fedora developers prefer to make upstream changes instead of applying fixes specifically for Fedora—this ensures that their updates are available for all GNU/Linux distributions. The best lite Linux operating system has a GNOME desktop by default which you can change to your wish. Fedora’s latest projects include the Fedora Spins by which you can customize and implement variations in the operating system desktop environment and UI. It uses the RPM package management system. Fedora has a comparatively short life cycle: version X is maintained until one month after version X+2 is released. With six months between releases, the maintenance period is about 13 months for each release. Fedora had reasonably good support for PowerPC when he used that processor architecture. Fedora comes with the default DNF package manager or GNOME software to install software and software repositories Download Link: Fedora for Desktop / Laptop Kubuntu Kubuntu is an official derivative of the Ubuntu operating system using the KDE graphical environment instead of GNOME. This netbook OS is part of the Ubuntu project and uses the same underlying system. It is possible to run both the KDE desktop (Kubuntu-desktop) as well as the Gnome desktop (Ubuntu-desktop) interchangeably on the same machine. The Kubuntu desktop is supporting to full customization. Originally designed to ease the transition for users from other operating systems (such as Microsoft Windows) by allowing a similar desktop layout, and the KDE 4 Plasma Desktop incorporates widget-centric modularity that allows the user to integrate function identical to all other operating systems. It is also creating new functionality not found in other operating system desktops. 3-D effects are available in the standard KDE4 installation.

  10. Hi all, I am in need of a good laptop, my budget is around 600-700 EUR (Prefer to spend 600), and the best deal I can find is this laptop: Acer A315-53G-551Y https://www.amazon.it/gp/product/B07FWBPJM4/ref=ox_sc_act_title_1?smid=A11IL2PNWYJU7H&psc=1 At time of posting, 610 EUR. Yes, I know that the screen is HD not FHD, but my budget is limited. I will use the computer for internet browsing, watching videos, playing games like AOE, and some light PS work. Is the graphics card able to handle PS or should I look at an Intel HD 520-620? I like NVidia but I am uncertain if this particular card is powerful enough. (It does say 2GB dedicated though). Any thoughts? I need to purchase a laptop very soon. Thanks in advance all! .
  11. As smartphones transitioned to becoming all-touchscreen faces, these newer keyboard-free designs were still considered smartphones. But remove the keyboard from a Windows laptop and you strip its identity, leaving you with a whole other class of device: The tablet. Indeed, the term "2-in-1" for a laptop with a detachable screen is a construct to accommodate iPad-inspired notions of what a laptop should be from a company that argued there really wasn't a standalone tablet category. Still, the term is particularly paradoxical. Microsoft did the most to popularize keyboards as integral parts of tablets, yet those products (like the Surface Pro), with nearly identical functionality, are not considered "2-in-1s" even when the keyboard covers are in the box. In any case, the convention highlights the historically strong association of laptops with keyboards. At the launch of the BlackBerry Key2, TCL Mobile justified the continued importance of keyboards on phones were by praising their primacy on laptops. As I argued in my last column, it's not an apples-to-apples comparison. Despite that, some momentum in the great keyboard debate has begun to flow the other way -- from smartphone to laptop. After all, some of the same justifications for keyboard elimination apply -- more flexibility, larger display area, fewer moving parts, and a thinner profile. Already, the attack on the bezel has already convinced a few laptop makers to relocate their cameras although convertible momentum remains strong. Still, there have been experiments. The first Surfaces, for example, said as much about the optional nature of a keyboard for a laptop as it did about the value it brings to a tablet. Microsoft even teased the possibility of a range of purpose-built covers such as a music mixing design. In 2016, Lenovo experimented with a flat, outlined keyboard area that doubled as a stylus drawing area on its Yoga Book clamshell devices for Android and Windows. To be sure, typing on those devices entailed a learning curve, and Lenovo plans for a Chromebook version never bore fruit. Still, when I wrote about the Yoga Books, I found them to be the first convertibles that could compete with slates as tablet form factors. Asus' "Project Precog" announcement at Computex -- a clamshell that replaces the input half with another display -- recalls an earlier effort by Acer with its first Iconia device in 2010. Indeed, even Apple's oft-maligned touch bar can be seen as clearing some runway for "bifold tablets." Once, the idea that Apple would remove the MacBook's keyboard was the stuff of Onion parodies. But the company, which has done more than any other to acclimate us to typing on glass, has filed a patent for a way to minimize reflection on the keyboard-area portion of a laptop that might lack one.

  12. With Yandex browser Your laptop will work longer The battery is always discharged inappropriately. Only enjoy the movie or find an interesting article — have to look for an outlet or turn off the notebook. Now it will happen less frequently if You use Yandex browser which has received a power-saving mode. We tested energy saving and compared it with normal mode Yandex browser, and other browsers (Edge, Chrome, Opera and Firefox). For this purpose we used a Dell Latitude 6330 with the operating system Windows 10. A special program simulated the operation of the Internet: open and scrolling, switching tabs. Our results: iXBT.com repeated this test using Asus ZenBook Flip S UX370UA and got the same result: New Yandex browser is the most energy-efficient browser on the market of the popular browsers. In the power saving mode Yandex browser: - reduces the activity of the background tabs; - always use the graphics card for video playback; - reduces the frequency of rendering the page; - disable animation in the interface elements browser, if she spends a lot of CPU resources; - disables the background animation on the new tab; - performs other functions to optimize power consumption. Energy saving works in the current version of Yandex browser (18.4.1.871). Energy saving starts automatically when you disconnect the laptop from the power source, but you can change this in the settings. Saving energy does not affect the level of comfort when browsing the Internet.

  13. There is a lot of distrust surrounding the Intel brand at the moment largely due to a sequence of events which included a slow disclosure of a serious security flaw (which appears to be getting worse), a secret early disclosure of this flaw to China (which has technical ties to North Korea), related patch problems, their CEO apparently fleeing Intel stock. This damaged trust and raised the question of why anyone would want to invest in a company, for product or stock, that the firm’s own CEO didn’t think was a good investment and this comes on top of the insider trading concerns raised by the activity. In the meantime, AMD released their strongest set of processors in their history, generally equal to or better than Intel’s offerings, and providing unique values in areas like single socket servers. Against that launch Dell, HP, and Lenovo brought out new products. However, it is interesting to note, that of the 3 HP was by far the most aggressive releasing entire lines of offerings. Let’s talk about why this could play particularly well for HP. The Importance of a Line When looking at what could become an industry pivot—Intel is struggling at the moment, buyers like to see a solid commitment on competing technology rather than tentative moves. If they are going to invest in the pivot early or take advantage of point price incentives, they like to see the vendor they are using is fully in. While single product targeted sales can be very powerful, as Apple has repeatedly showcased, that approach comes with a massive marketing requirement which only Apple, and occasionally Samsung, have been willing to step up to. And even then, it has rarely worked in the commercial space generally being more effective with consumer offerings. These new AMD-based lines are commercial offerings. Thus, releasing lines for both desktop and mobile use better fit within the traditional PC OEM’s product model and should perform better than the single or dual product offerings of HP’s competitors. HP Stepping Ahead of Their Competitors HP stepped ahead of their competitors to release 4 new notebooks and a whopping 5 new desktop systems with this launch. Standing out from the group were the HP EliteBook 735 G5 with a 13.3-inch screen which is arguably the most compelling AMD based laptop ever produced and more than comparable to its Intel counterpart and the small form factor HP EliteDesk 705 Mini G4 which provides a near perfect blend of size and performance for most desktop implementations. Across the board, the products are both well-priced and have unusually attractive designs easily equaling their Intel based counterparts but priced so that, effectively, the user is getting discrete Vega graphics for free. Given how increasingly applications are using GPU compute over CPU compute this not only provides an initial performance advantage but should allow these products to remain in service longer, further lowering the total cost of ownership for an AMD-based system. One Life The attractive designs surrounding both desktop and laptop lines flow out of HP’s unique One Life strategy, which speaks to the fact that users aren’t either employees or consumers, they are both. This means, and this has proven particularly true of Millennials, that users want tools they can be proud of. Surveys have highlighted that potential employees will favor companies that give them better tools. This learning has driving IT buyers to allow for more attractive offerings and speaks to why HP is outgrowing their competitors of late. They are simply more aggressively providing the tools that users want and IT buyers are increasingly driven by those user wants (something many of us have been tracking for over a decade). Security Given Intel’s weakness surrounds some unfortunate security decisions made by that company, HP’s security first strategy appears to also be resonating. Surrounding their offerings is a unique set of security tools that provide self-healing for BIOS and Firmware, assures that malware can’t shut down critical services, helps the user avoid contaminated web sites, provides multi-factor authentication, and even has a surprisingly unique privacy camera option to prevent spying. One other feature I’m surprised is unique to HP is an integrated optional electronic privacy screen. I think every laptop should have one of these as it prevents the person sitting next to you on a plane, or other public space, from seeing what you are working on. These things should have been a requirement years ago but, currently, only HP is offering them broadly. Wrapping Up: HP Steps Up Markets are often defined by companies that step up to a challenge and—against the current Intel crowd—only HP is fully stepping up to the opportunities represented by AMD alternative PCs. With two strong PC lines that are both attractive and well-secured they have taken the unusual path to being what is likely the safest product heaven for business PC buyers. I expect the market will reward their risk given the growing concerns surrounding Intel. There is an old saying “go big or go home” apparently HP is following it with their new AMD lines which are helping define HP as the PC company to beat this decade. Source
  14. One of my friends brought a Lenovo laptop, Lenovo ThinkPad E41-15 yesterday to my attention requiring to install windows 7 in it. I did that and went to lenovo support for drivers. The strange thing is I can install all the drivers successfully but windows can't verify their their digital signature. Come on microsoft, those are OEM drivers! Here what I have tried so far- I verified MD5, SHA-1 and SHA-256 of the driver files with the hashes given on the download page. They all are intact. Tried installing the drivers by disabling the driver signature verification. No problem in that case - everything works just fine but only for the session. After you restart, driver signature verification fails and system switches to generic VGA driver instead of Radeon R4. Tried force install the driver but it shows signature verification error (the driver is installed BTW, it is just windows is not allowing to use it). I don't know what is there left to try.
  15. Hello fellas I've got an Acer one 10 s1002 2in1 convertible tab/laptop to format. I need to format it because the device is severely infected. So the device came with windows 10 home 32-bit pre-installed. It has a 32 GB eMMC (no HDD). Acer has driver support only for win 10 and win 8.1. So I have tried formatting with both but couldn't succeed. During boot I entered the BIOS and changed the boot order adding my bootable media in first place to boot from there. But after I exit the BIOS saving the changes that I have made, it boots from the internal eMMC, not from my bootable media. I also tried pressing F8 during restart to get to the boot menu and directly selected my bootable media but instead of booting from my media, it takes me to the BIOS. I also tried disabling the secure boot but no use. The unbelievable thing is I have disabled all other boot orders in BIOS including the internal eMMC and only allowed the one in order #1 which is my bootable device but yet after restart it boots from the internal eMMC completely ignoring the BIOS settings. So what do I do?
  16. If there's one thing Mark "Chris" Sevier loves, it's jerking off. If there's another, it's filing lawsuits. The man who sued Apple because it sold him a computer that allowed him to get addicted to porn is now getting involved in Florida's gay marriage debate by demanding he be allowed to marry that same porn-infested computer. Florida is considering the very serious question of whether it will recognize same-sex marriages performed in other states, and Sevier has filed a motion claiming to represent other minority sexual orientation groups. If gay people "have the right to marry their object of sexual desire, even if they lack corresponding sexual parts," he argues, "then I should have the right to marry my preferred sexual object." Because the gay marriage debate is all about objects and parts, not relationships, families, and the legal benefits that accrue to married couples. Obviously. Unfortunately, Sevier's 24-page filing continues with a description of his personal relationship with his sweetheart—I mean, preferred sexual object: Over time, I began preferring sex with my computer over sex with real women. Naturally, I 'fell in love' with my computer and preferred having sex with it over all other persons or things, as a result of classic conditioning upon orgasm. Sevier, an attorney and music producer, has a history of strange legal entanglements, includingstalking country singer John Rich and suing A&E for firing one of Duck Dynasty's beardos over homophobic remarks in an interview. He was suspended from practicing law in Tennessee in 2011 due to "mental infirmity or illness." Sevier's attempt to marry his MacBook have been squashed for now in Florida. "Chris Sevier has moved to intervene, apparently asserting he wishes to marry his computer," Judge Robert Hinkle wrote on April 24. "Perhaps the motion is satirical. Or perhaps it is only removed from reality. Either way, the motion has no place in this lawsuit." But Sevier isn't done yet. If Florida won't let him get hitched to a computer, maybe another state will. He's currently attempting to intervene in Utah's battle over a state constitutional amendment banning gay marriage. "Those of us whose sexual orientation has been classically conditioned upon orgasm through the straight forward science of dopamine to prefer sex with inanimate objects and animals do not have public support, like the gays, so we are especially vulnerable here," he wrote in a 50 page brief.

  17. A leaked video demo reveals the HP Slatebook 14 – an Android-powered laptop with a 14″ 1080p touchscreen. It’s not a hybrid (detachable tablet + keyboard dock) like the Slatebook X2, nor is it a dual-boot device, it’s pure Android. The specs are a bit unclear, but the video is promising a slim and lightweight design. Without the need for a second battery behind the screen like on the Slatebook X2, this new device should be thinner than 20mm. It’s positioned as an affordable device, though so we shouldn’t expect anything too cheap. The body seems to be made of polycarbonate and will likely be available in bright colors. The HP Slatebook 14 features a 1080p screen, but a cheaper version with a lower screen resolution might be available too. It will be powered by Tegra 4 with rumored 2GB RAM and 16GB storage, expandable via a microSD card slot. The Android version is unclear, but it’s rumored to be 4.2 Jelly Bean. There are also three full size USB 2.0 ports, a full-size HDMI port, Wi-Fi and Bluetooth. The connectivity features include a SIM card slot, presumably for HP DataPass. The Slatebook 14 also packs Beats audio speakers. Note that the HP Slatebook 14 isn’t official yet, but with Computex 2014 just around the corner (it starts June 3) it should be announced fairly soon. Until then, check out the video in question: http://<object id="flashObj" width="480" height="270" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,47,0"><param name="movie" value="http://c.brightcove.com/services/viewer/federated_f9?isVid=1&isUI=1" /><param name="bgcolor" value="#FFFFFF" /><param name="flashVars" value="videoId=3507630053001&linkBaseURL=http%3A%2F%2Fh20621.www2.hp.com%2Fvideo-gallery%2Fus%2Fen%2Fproducts%2Flaptops-and-notebooks%2Flaptop%2F3507630053001%2Fhp-slatebook-14-video-demo%2Fvideo%2F&playerID=1111577658001&playerKey=AQ~~,AAABAeI3VIE~,N0OfmZCPaxgxui0PhG4ilXrKUlL_O1tR&domain=embed&dynamicStreaming=true" /><param name="base" value="http://admin.brightcove.com" /><param name="seamlesstabbing" value="false" /><param name="allowFullScreen" value="true" /><param name="swLiveConnect" value="true" /><param name="allowScriptAccess" value="always" /><embed src="http://c.brightcove.com/services/viewer/federated_f9?isVid=1&isUI=1" bgcolor="#FFFFFF" flashVars="videoId=3507630053001&linkBaseURL=http%3A%2F%2Fh20621.www2.hp.com%2Fvideo-gallery%2Fus%2Fen%2Fproducts%2Flaptops-and-notebooks%2Flaptop%2F3507630053001%2Fhp-slatebook-14-video-demo%2Fvideo%2F&playerID=1111577658001&playerKey=AQ~~,AAABAeI3VIE~,N0OfmZCPaxgxui0PhG4ilXrKUlL_O1tR&domain=embed&dynamicStreaming=true" base="http://admin.brightcove.com" name="flashObj" width="480" height="270" seamlesstabbing="false" type="application/x-shockwave-flash" allowFullScreen="true" allowScriptAccess="always" swLiveConnect="true" pluginspage="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash"></embed></object> Source
  18. Seed Phone offers a unique way to converge multiple devices using a single smartphone A computer engineering student from the University of Cape Town has come up with a unique way to transform a smartphone into anything from a laptop to a games console. In an effort to eliminate the disjointed experience of using multiple devices across different platforms, Nick Rout developed Seed - a range of laptop, tablet, TV and console hub prototypes capable of converging around a single smartphone. "While our devices are individually really capable, using them together is quite disjointed," Rout tells IBTimes UK. "These devices all have different operating systems. An app might work on one and not another, your files are often scattered across them in an unorganised fashion and settings/preferences differ from device to device." A multi-faceted approach Having previously relied upon an ad hoc solution of cloud services and portable storage, Rout decided to transform his current smartphone - a Google Nexus 4 - into a range of devices that he designed. A 3D render of the Seed concept. A 3D Prited prototype of the Seed Phone. The Seed Phone magnetically docked into the Tablet. The Seed Phone docked into the laptop prototype. The Seed Phone docked in the TV/ games console hub. Inserting the cylindrical magnets into the Nexus 4 case. In developing prototypes that locally synchronised all of a user's data into one multipurpose device, Rout also sought to overcome a number of other tech-related problems that modern devices encounter. The ones he identified with the most included poor battery performance, the high cost of owning a whole set of devices and the ever-growing concern of data security. For it to work, Rout needs an operating system that can handle convergent user-interface switching. Fortunately, the Ubuntu OS will be offering this exact functionality in the very near future. "This multi-faceted approach aims to unify the disparate user experience one encounters when hopping from mobile to desktop to tablet and back again," writes Joey-Elijah Sneddon, editor of OMGUbuntu. The success of Seed will therefore likely depend heavily on the success of this new operating system, unless a significant contender - like Apple or Microsoft - moves into the space. Growing the idea The cost of development has so far come straight out of the student's own pocket but Rout is currently in talks with a number of potential investors. A crowd-funding campaign is also expected in the near future. "My hope is that it would reach consumers within six months to a year of development," Rout says. While products like the Motorola Atrix and the Asus Padfone have previously experimented with portions of what Seed would offer, none has yet achieved widespread commercial success. Could Seed be any different? Rout seems to think so. "The devices only offered convergence between two form factors and the docks they created were too expensive. Seed aims to change all of this."

  19. Hey guys. I am going to get my daughter a new laptop for her birthday. Here is the deal: 1) I have about $450 to spend 2) She will be happy if the laptop plays Netflix smoothly and if she can Skype smoothly (our internet is fast so that is not a concern, I am speaking of the video motion of Netflix and video conferencing like Skype being smooth with the Intel Integrated GMA HD Graphics Card...i think its an Intel HD Graphics 2500) 3) Here is what I am thinking about getting her: http://www.newegg.com/Product/Product.aspx?Item=N82E16834314249 4) What do you think? 5) Thanx
  20. By Austin McIntire 2 hours ago While Internet Explorer is often treated as the red-headed step child of web browsers, there is one area in which Microsoft's browser has traditionally reigned supreme, battery life. Microsoft's own research has demonstrated IE's power efficiency, and recent test results from the website 7tutorials have once again proved that IE enables user to eke out the maximum amount of battery life from their Windows laptops and tablets. This particular test relied on the Peacekeeper battery test and was performed across a variety of devices including a Toshiba Encore 8" tablet, a Surface Pro 2, and an older HP Pavilion laptop. Each round of testing compared the performance of the latest versions of Internet Explorer (touch and desktop), Firefox, Chrome, and Opera web browsers. On the Toshiba Encore, the touch version of IE trounced the competition with a run time of 8 hours and 52 minutes, compared to 7:45 for the desktop version of IE. The other three browsers produced similar results with approximately 6 hours of battery life. The battery test on the Surface Pro 2, however, produced some rather odd results. The touch version of IE exhibited a battery run time that was an hour less than the desktop version of IE, an inversion of the results from the previous test. It even performed worse than the Firefox and Opera web browsers. These results are especially confusing given that both the Encore and Surface tablets run full (non-RT) versions of Windows 8. It appears that there are still some Surface Pro 2 firmware issues that remain to be addressed. http://www.neowin.net/news/internet-explorer-still-provides-the-best-laptop-and-tablet-battery-life
  21. By Kannon Yamada 21 May 2013 Would you believe that many computers and smartphones can run cooler and consume less power? A trick exists, called undervolting, which can increase your CPU’s efficiency with few drawbacks. If performed right, devices generally produce less heat while exhibiting improved battery performance. The process can require a great deal of patience and confidence as the potential for disaster exists. Only the stouthearted should even make an attempt. For those of you looking for quicker solutions to reduce battery drain, check out Tim’s excellent article on mainstream methods of cooling your computer down. This article introduces undervolting to the uninitiated, focusing on explanation, methods of implementation, the available compatible hardware and what software exists. For a more detailed guide on how-to undervolt, check out this instructional guide. Undervolting Explained After an intense session of Call of Duty or Modern Warfare 3, you may notice your computer or graphics processor getting unusually hot. That’s because a simple relationship exists between the the speed at which a device runs and its temperature. When you use your computer to perform CPU intensive tasks, it will run at a higher frequency, and thus produce greater heat, than it would at idle. There’s a formula that electrical engineers use to explain this relationship. Unfortunately, I wasn’t smart enough to be an engineer so my understanding is weak, but here goes: P = V^2/R, where power is equal to voltage squared, divided by resistance. As you can see from the equation, lowering voltage has a tremendous effect on power. But the question remains: How could it be possible for us to lower voltage while maintaining performance? Keep in mind three factors: ◦Not all CPUs are the same: Because of the ridiculously complex manufacturing required in fabricating a processor, no two CPUs are exactly the same. Rather than responding identically to voltages, CPUs exhibit a range of tolerances. Consequently, the companies that make processors established a baseline voltage that most CPUs can use without issue. Unfortunately, this voltage is oftentimes higher than required and produces a great deal of waste heat as a byproduct. Because of this, the majority of CPUs can actually use a lower voltage a various frequencies. ◦A CPU’s speed progression isn’t linear: A computer’s speed varies from its top-rated clock cycle, typically measured in gigahertz, to its lowest possible speed. The progression between its fastest and slowest speed does not move in a linear fashion, but in a stepped pattern. I’ve seen differing terminologies for these “steps” on differing CPU architectures. For the PC (x86), I’ve seen it referred to as P-states. ARM does not appear to have a similar naming convention. ◦You can decrease a CPU’s voltage: CPUs exhibit a range of voltages tolerances across frequencies. For example, using special software you might lower the voltage (sometimes referred to as a “VID“) at different frequencies. If too low, it will cause crashes and blue screens, so caution is advised.  Three Steps To Undervolt a Device ◦Backup Your Information: In case something goes catastrophically wrong you may get permanently boot-looped. Therefore it’s crucial to have your information backed up. ◦ Gradual Voltage Changes: Whenever you lower your voltages, there’s always the possibility that it will cause a reboot. Some handheld devices enter what’s known as the “sleep of death“, which means the phone requires a hard reset. If you saved your voltages this can result in an unbootable condition, since it loads up unstable voltages. Remember to gradually move the voltages down (and never above the default value!) and then rigorously stress test at each step. However, it’s important to note that the multipliers associated with faster processor speeds undervolt more efficiently than those at lower speeds, since the highest speeds produce the most amount of heat. On mobile devices, undervolting makes the biggest difference in both energy consumption and heat production. ◦ Stress Testing: After moving your voltages down one multiplier, you will want to stress test rigorously. Stress testing software for both Android and PC exists, which make this process much easier. It simply runs your CPU at the fastest possible speed, or at a range of frequencies. Simply set your undervolt value and then fire up your stress testing software. For Desktops & Laptops Some desktops and laptops can alter their voltages through their BIOS. Different motherboard manufacturers, unfortunately, use differing terminologies: Some use the term “voltage offset“, which reduces voltages uniformly across all steps. Other boards only reduce voltages at the highest CPU frequencies – you should Google your motherboard’s make plus the search term “undervolt” or “voltage offset“. For example, my undervolt settings from my EFI (it’s basically a BIOS): Intel CPUs: Unfortunately, Intel chipsets, Sandy Bridge and later models, do not benefit in any substantial way from lowering voltage. While my own experiences show some impact on temperature, the experts believe otherwise. The most common method of undervolting older Intel CPUs is ThrottleStop for the Windows OS. Throttlestop lowers voltages across a range of CPU frequencies – simply check the “Set Multiplier” box then reduce the “VID” number to drop voltages. AMD CPUs : particularly its Brazos, Llano and Trinity lines, can undervolt with great effect. One of the best examples is the undervolting software available for the Brazos series of CPU/APU. The software used to manipulate voltage values is known as BrazosTweaker. There’s also FusionTweaker. Users report up to 30% reductions in temperatures and solid increases in battery life. For AMD chipsets, other voltage manipulation methods exist, such as PSCheck and AMD Overdrive. However, although PSCheck is the best program, it’s also the hardest to get hold of. I ended up biting the bullet and installed a zip from a complete stranger’s Dropbox—that’s always a terrible idea and you should never do that, unless you’re me. In which case you make regularly poor decisions and installing strange files from sketchy sources is the least of your worries. Stress-Testing: To stress-test your device, simply lower your voltage by a single step and then fire up the stress testing software. In my experience anywhere from 5-10 minutes of testing is sufficient. If the computer crashes or freezes, move the voltage back up at least one step before moving onto the next multiplier (sometimes referred to as a P-State, pictured below). Continue repeating the process at each stepping point, lowering the voltage until instability occurs. Notice that as frequencies increases, so too does voltage. The best software for stress-testing is Prime95. Prime95 runs complex mathematical formulas on your computer, which causes the the CPU to run super hot. If you’ve set the voltage too low, your computer will crash and you’ll know the absolute lowest limit of your processor’s voltage tolerance. Approximately 5-10 minutes of stress testing should weed out incorrect voltages. From the Prime95 “Run a Torture Test“, make sure to select “Small FFTs“. We’ve discussed undervolting on MakeUseOf before for laptops. Also, read about Tina’s breakdown of some mainstream solutions for getting your heat under control. Tablets, Smartphones & Android Powered Devices Before attempting to undervolt your device, you must have root access (link goes to SuperOneClick) and you should have installed a custom ROM supporting undervolting. While, technically, you only need a custom kernel that supports UV, most custom ROMs include a custom kernel. Most cell phones with a custom kernel and the right software can undervolt – however, doing so requires special firmware, or software that exists at a level higher than the operating system. Firmware is stored on solid state memory in an area normally inaccessible to the end-user. However, if you have the right firmware, some software can modulate the voltage fed to the CPU. My favorite software for undervolting is IncrediControl. Just run the app and select the “SVS” tab from the top menu bar. From there, you must use extreme caution. Proceed to lower voltages one step at a time. I recommend only lowering the voltages on the two or three highest frequencies; as indicated by the power equation, reducing voltages at higher frequencies has a greater impact on overall heat production. Stress-Testing: For stress-testing, to my knowledge there’s only one app worth using: StabilityTest. Simply choose either “Classic Stability Test” or “Scaling Stability Test“. If you only intend on undervolting your highest CPU frequency, the classic test should suffice. However, if you plan on undervolting a range of values, go for the scaling test.  Conclusion Cooling down your devices and getting better battery life takes only three steps: First, backup your device. Second, make gradual voltage adjustments. Third, stress test each time you make a voltage adjustment. For Android devices, this requires that you have root access and have installed a custom ROM. For computers, you must have a newer AMD chipset, such as Llano, Brazos or Trinity. On Intel system, you must have Core2Duo or thereabouts. Remember to never raise your voltages above the default value. Raising your voltages will likely destroy your computer.
