Lenovo laptop: Annoying beep sound at startup

9 posts in this topic

Today a friend came to me with his Lenovo laptop to look after a problem. When I switched it ON, after loading the BIOS, it starts producing a annoying "beep" sound till it completes loading the "advance boot" menu. Then I select "Start windows normally" then windows loads normally and no problem onwards till next startup.

Any suggestions?

How many times have you heard sirens or incessant beeping? Do not worry, there's no time bomb or chissacché housed in your PC ... simply, the so-called "Beep", are nothing but signals that the BIOS sends us in certain situations, from the normal to the emergency. Let us try to interpret them.

Here seguto, are the various codes of BIOS Beep most commonly installed on motherboards. To recognize what type of BIOS you have, just look at during the POST (start)In case you are faced with AMI BIOS (American Megatrends), the signals may be in the form of short or long beeps alternated.

Beep Signals - Name Error - Meaning

1 short - DRAM Refresh Failure - Error in DRAM refresh. Act on it.

2 Short - Parity Circuit Failure - Error in DRAM Parity control. Acting on RAM.

3 Short - Base 64K RAM Failure - Error of the first 64K of RAM or video memory.

4 Short - System Timer Failure - Error Timer motherboard. If possible, take action on the latter.

5 Short - Processor Failure - Error Processor.

6 Short - A20 Keyboard Controller Error - Controller A20 of tasatiera.

7 Short - Virtual Mode Exception Error - The processor has generated an error. It might be a mistake processor or motherboard.

8 Short - Display Memory Read / Write Test Failure - Error of the video card's memory. If the error persists, change the video card.

9 Short - ROM BIOS Checksum Failure - Problems in the BIOS. If possible, remove and re-flash the BIOS.

10 Short - CMOS shutdown Read / Write Error - Backup battery low. Provide for replacement.

11 Short - Cache Memory Error - in the second-level cache.

1 Long, 3 Short - Conventional / Extended Memory Failure - Memory test failed.

1 Long, 8 Short - Display / Retrace Test Failure - Error Access Lvl to the video card.

If however you were to deal with an Award BIOS, you will have the signals much more general and vague.

Beep Signals - Meaning

Along Repeated 1 - DRAM memory error. Act on it.

1 long, 2 short - Indicates a problem with the video card or the memory mounted on it.

1 Long, 3 Short - Video card error.

1 Along Continued - Generally indicates a problem with RAM, but sometimes also with the video card.

More ... - If you heard different signals, it is still problems with RAM or video card.

In the case finally, you were dealing with a Phoenix BIOS, you must pay close attention to what you feel, because this type of BIOS emits signals from intervening pauses, which will be marked in the table by means of the "+".

Beep Signals - Meaning

1 + 1 + 3 - Error reading the CMOS settings. Try a Clear-CMOS or disconnect the battery for 1/2 hour approx.

1 + 1 + 4 - Error BIOS. If possible, remove and re-flash the BIOS.

1 + 2 + 1 - Error on-chip timer.

1 + 2 + 2 - Error on the motherboard.

1 + 4 + 2 - memory error. Act on it.

2 + 1 + 1 - Video card error or memory.

3 + 2 + 4 - Controller Error mouse or keyboard.

4 + 2 + 1 - Error of the chipset.

4 + 2 + 4 - Error of the sound card or modem.

4 + 3 + 4 - Backup battery low. Provide for replacement.

4 + 4 + 1 - Error of the serial port.

4 + 4 + 3 - math coprocessor error (error now internal to the processor).

That's it, now when the BIOS we will "talk", we'll know asoltare, even if in the end, we hope that he is always up!

Beep count: All beeps are short.

2 beeps before the advance boot menu loads and for each option that load on the menu, accompanies a beep.

possible problem with the (4 + 4 + 3 - math coprocessor error (error now internal to the processor).

May be. It's a sandy bridge i3-2310m 2.1 Ghz.

wait for further advice - suggestions from others to better understand and get yourself a 'more thorough idea to the problem. :) ;)

That is what I call Appropriate Information for a given problem.

What kind of Lenovo laptop? if it is a Thinkpad, it could be beep sound from modified BIOS because of white list WWAN/WLAN cards.
