BIOS beeps when you turn on the PC. AMI BIOS - beeps (error codes)

Greetings, friends! Today I will tell you about BIOS beeps. You may have noticed that when you turn on your computer, it beeps or, in other words, beeps. In fact, this is beeping your computer's BIOS, thereby telling you if everything is fine with your computer or if there are any problems. Let's try to understand this topic in as much detail as possible.

What do BIOS beeps mean when you turn on your computer?

Whatever BIOS is installed on your motherboard, when you turn on the PC, you should hear one short beep. This means that everything is working fine and after it starts loading Windows. However, sometimes the opposite is true. The BIOS squeaks like crazy, and the computer either does not turn on at all, or else the inclusion ends on the very first black screen - the BIOS bootloader.

This is where today's knowledge will come in handy. Because by this beeping you can determine what exactly is out of order in your PC.

Well, have you already looked at what BIOS you have? Now you can look at the decoding of BIOS audio signals.

AMI BIOS beeps. Full transcript

1 short	Everything is working properly. Pay no attention to him.
2 short	The RAM is not working properly or is defective. Try to disassemble the system unit, remove the RAM from the slots and insert it back. Perhaps this will solve the problem. Otherwise, you will have to contact a service center or buy a new RAM.
3 short	Almost the same as 2 short beeps. Do the same as in the previous paragraph.
4 short	You have something wrong with the system timer on the motherboard. Try resetting BIOS to factory settings. If that doesn't help, then try replacing the battery, it's cheap.
5 short	One of the worst mistakes ever. Your CPU is faulty. A simple restart of the computer may or may not help.
6 short	Check if the keyboard is connected properly. If yes, but the BIOS still beeps, then you will either have to replace the keyboard or repair the connector on the motherboard.
7 short	It's also scary. The motherboard is faulty. And it would seem that 7 is a lucky number. Such a surprise.
8 short	Transcendent to your video card. Although, try to pull it out and insert it back into the slot, maybe that will help. In the same case, if the video card is integrated, you will have to replace the entire motherboard or take it to a service center. Although I would not advise, if they fix it, then not for long.
9 short	You need to update or flash the BIOS of your computer.
10 short	CMOS memory error. Take it to the service center, they will help you.
11 short	This error is also related to RAM.
1 long and 1 short	The power supply is not working properly (or not working at all, you know better).
1 long and 4 short	The video card is not connected. Have you forgotten anything?
1 long and 8 short	You have not connected a monitor or the video card has a problem with displaying images on the monitor.
3 long	RAM is not working properly.
5 short and 1 long	There is no RAM. Insert it please.
Infinitely long	This is either overheating of the computer, or problems in the operation of the computer's power supply. So the BIOS beeps, which has stress, shock and severe panic.

Decoding of BIOS AWARD audio signals

1 short	It's all right, don't worry.
2 short	Minor error in BIOS settings. Enter BIOS settings and reset it to optimal settings or cancel your last setting if you remember what exactly you changed.
3 long	This is a keyboard. Try restarting your computer.
1 short and 1 long	RAM is not working properly. Disassemble the system unit, remove the RAM from the slots and insert it back. If the problem persists, then you will have to contact the service center or buy new RAM.
1 long and 2 short	Problems with the video adapter, or rather video memory. Perhaps everything will be fixed if you remove the video card from the slot and insert it back. If the video card is integrated, you will either have to switch to a discrete one or replace the motherboard.
1 long and 3 short	Keyboard connection error. Try another keyboard if you have one. If the BIOS keeps beeping, then most likely the problem lies in the motherboard.
1 long and 9 short	BIOS needs to be flashed. It is better to do this at a service center if you are not sure that you can handle it yourself. And then you can lose the motherboard forever.
Infinitely repeating short signal	Problems with the power supply. It is buggy and can burn other components of your computer.
Infinitely repeating long beep	BIOS AWARD beeps in this way if your RAM is damaged. Possibly just one of the bars. Try it one by one

Here's how Phoenix BIOS beeps in a special way

BIOS Phoenix squeaks a little differently than its counterparts. It is more melodic, if I may say so in this context. Phoenix BIOS dot beeps alternate with pauses between them. And absolutely all the signals of that BIOS are always short.

1-1-2,	BIOS detected errors in the operation of the central processor.
1-1-3	Error reading information from the CMOS memory of the motherboard.
1-3-2	Unable to run RAM test.
1-3-3, 1-3-4	One of the RAM controllers is damaged.
1-4-1,	These BIOS beeps indicate errors in RAM.
3-3-1	The battery on the motherboard is dead or low.
3-3-4,	BIOS errors indicating the incorrect operation of the video adapter.
4-2-3	Check keyboard connection.

BIOS does not beep when you turn on the PC

Quite often it happens that when you turn on the PC, the BIOS does not beep at all. Why? Depends on the specific situation. To be in the subject, first you need to know what a speaker is and why you need it.

What is a motherboard speaker?

Motherboard speaker is a miniature tweeter that warns the user of malfunctions in the operation of your computer even before it is turned on. In other words, the speaker is a means of displaying information about the state of the computer. Also, the speaker is a device that emits BIOS beeps!

Here is what the speaker looks like on the motherboard. It is he who helps to emit BIOS signals!

Some reasons why the PC may not beep at startup

It often happens that manufacturers of budget computers (and not only budget ones) either forget to install a speaker on the motherboard, or deliberately save on this spare part. Accordingly, the BIOS does not beep, because there is simply nothing to beep. If you urgently need to diagnose a problem with your computer, you can simply borrow a speaker from your friend for a day. Fortunately, pulling it out and inserting it will not be difficult for you.

Another reason why you may not hear BIOS beeps when you turn on the computer is that you accidentally touched it or pulled it, and it just detached a little. In this case, insert it more tightly and everything will squeak with you. By the way, there are also such motherboards in which the speaker does not disconnect at all.

BIOS does not beep on laptops, because the speaker is not installed on them for aesthetic reasons. Imagine if every time you turn on your laptop, it gave you a characteristic, high-frequency signal. It's annoying.

Especially if the wife is already asleep, and you decide to play tanks in secret, turn on your laptop, and here you are BEEEEEEE!!! The wife immediately woke up and filled you with a star. In general, the speaker is not so relevant on a laptop.

Although some laptops can output similar beeps through external speakers and even through headphones. Everyone who encounters this is trying to get rid of this squeak (peep) as soon as possible by any means.

Where and how to connect the speaker on the motherboard?

You will need to know this if you still decide to borrow the missing speaker from a friend or buy it. When you took the speaker out of a friend's motherboard, you should have noticed that the place of its connection is marked with characteristic inscriptions, most often it appears there speaker or spk or spkr. Polarity for the speaker does not matter, so you can connect the speaker accurately.

A few examples of motherboards with marked places for connecting a speaker.

Summarizing

The article turned out to be quite voluminous, but I hope it helped you understand today's topic. At a minimum, you can now connect the speaker to the motherboard and know why you need it. We also examined the decoding of sound signals for the main and most popular BIOS versions. If your BIOS version differs from those considered, then just specify your request in the search engine, for example " decoding sound signals BIOS IBM / DELL».

It often happens that even an experienced system administrator forgets BIOS codes and signals (especially since new motherboards are already fully equipped with UEFI), to say nothing about a non-professional. Yes, and knowledge of the signals will help you quickly, and in everyday cases, also often free of charge to solve the problem with a non-starting computer or laptop.

This is what BIOS chips from AWARD AMI and Phoenix look like.

By the way, for reference: BIOS is a Basic Input-Output system or in Russian speaking, the basic input-output system. In other words, this is a low-level program that is hardwired into the chip of your computer's motherboard. The BIOS is loaded when the computer is turned on and is responsible for initializing its hardware components, checking their performance and correct startup. Then, the bootloader program is launched, which launches the Windows, Linux operating system, or whatever you have installed there ...

Here we need to make a small digression and tell you that the signals of this very BIOS may differ depending on the manufacturer. Consider the most popular options, there will be three of them - AMI BIOS, AWARD BIOS, Phoenix BIOS.

Under the cat is a table describing BIOS errors.

AMI BIOS beeps

In all AMI BIOS versions, the successful completion of the self-test is one short beep, after which the installed OC is loaded. I indicated other AMI BIOS beeps in the table:

Sound signal	Description
2 short	RAM parity error
3 short	Protected sector error 64 KB RAM
4 short	Motherboard system timer failure
5 short	CPU failure
6 short	Keyboard error
7 short	General motherboard failure
8 short	Video card memory failure
9 short	BIOS checksum error
10 short	Unable to write to CMOS
11 short	RAM error
1 long and 1 short	Power supply failure
1 long and 2 short	Video card error
1 long and 3 short	Video card error
1 long and 4 short	Missing video card, video card not found
1 long and 8 short
3 long
5 short and 1 long	No RAM
constant signal

AWARD BIOS beeps

With the correct post-test signal, everything is the same as in the previous version - one short AWARD BIOS beep means that everything is OK.

The rest of the signals are somewhat different - look at the table:

Sound signal	Description
1 short, repeated	Power supply failure
1 recurring, long
3 long	Keyboard error
1 long and 1 short	RAM failure
1 long and 2 short	Video card error
1 long and 3 short	Keyboard error
1 long and 9 short	ROM read error
1 long and 8 short	Monitor not connected, video card problems
3 long	RAM problems, memory test failed
constant signal	Problems with the power supply, PC overheating

Phoenix BIOS beeps

The third version of signals from Phoenix. BIOS from this manufacturer is becoming less common, but nonetheless.

Here I must say that everything is not the same with him as with the previous two. Yes, yes, the guys decided to show off, and not like everyone else, their signals are not double, but triple. In practice, this only means that, for example, a signal about problems with the power supply to the video card will look like three short beeps, a pause, three short beeps, a pause, then 4 short beeps. In the table, I will write them down as 3-3-4. So let's go...

Error codes from Phoenix:

Sound signal	Description
1 – 1 – 2	CPU error
1 – 1 – 3	CMOS write error, motherboard failure fees
1 – 1 – 4	BIOS ROM checksum error
1 – 2 – 1	Faulty interrupt timer
1 – 2 – 2	DMA controller error
1–2 – 3	DMA controller read or write error
1 – 3 – 2	RAM error
1 – 3 – 3
1 – 3 – 4	RAM controller error
1 – 4 – 1	Address RAM error
1 – 4 – 2	RAM parity error
3 – 2 – 4	Mistake keyboards
3 – 3 – 1	Battery failure CMOS on the motherboard
3 – 3 – 4	Video card failure
3 – 4 – 1	Video card failure
4 – 2 – 1	System timer failure
4 – 2 – 2	CMOS error
4 – 2 – 3	Keyboard malfunction
4 – 2 – 4	CPU operation error
4 – 3 – 1	Error in RAM test
4 – 3 – 3	Timer error
4 – 3 – 4	RTC error
4 – 4 – 1	Serial port failure
4 – 4 – 2	Parallel port failure
4 – 4 – 3	Coprocessor problems

I just want to add that in the case of self-repair of a PC or laptop always unplug it from the mains and only then you can safely climb inside armed with a screwdriver and other necessary tools.

In the next article I will talk about UEFI. What is it, why did she come to us and other interesting points.

P.S. In some cases with memory errors, it helps to pull the memory sticks out of the slots, wipe the contacts of the RAM cards with an ordinary soft eraser and the memory is back in service! If the memory does not burn out, but simply fails, then you can also try to swap the boards with RAM in places by banks, provided that the memory itself that you change in places is the same.

P.P.S. At the end of this article, I simply post tables of three BIOS codes in the form of pictures. They can be used as a cheat sheet by saving to your phone, tablet or computer.

Cheat sheets describing BIOS signals for printing

It seems to be everything that I wanted to write - I wrote it. Tried clearly and without water, as always. If there are any questions, I answer in the comments.

In contact with

An attentive user may notice that the computer makes sounds when it is turned on. Usually this is one short beep of the speaker (device on the motherboard). But other signals may be emitted during operation. Read about what they mean and how to find out what to do with them in this article.

The first step is to find out which one you have. You can find out about this when you turn on the computer, when letters appear on a black background. Search above or below for abbreviations AMI or AWARD BIOS.

Learned? Then let's go!

BIOS BEEPS: AMI BIOS

Two short beeps from the speaker mean some kind of malfunction in the computer's RAM.
How to solve the problem: remove the memory module from the slot, wipe it with a dry brush and insert it into place. If, after starting the PC, the signals are repeated, then further testing of the memory or its complete replacement may be required;

How to fix the problem: flashing the microcircuit or its complete replacement;

The absence of speaker signals may indicate a malfunction of the power supply.
How to fix the problem: we check the fastening of the power supply plugs to the connectors on the motherboard, we clean the power supply from dust. If as a result of the actions taken, when you try to turn on the computer again, there are no signals, the power supply needs to be repaired.

Separately, it should be noted the continuous sound signals of the BIOS that change in tone. This can be caused by either a faulty power supply or an overheating PC.

Now you know about BIOS sounds and how to decipher them.

Below are the beep values of some motherboards.

Award BIOS

- No signals - The power supply is defective or not connected to the motherboard.

— Continuous signal — Faulty power supply. Replacement required.

— 1 short beep — No errors found. The typical behavior of a healthy computer is that the computer boots normally.

— 2 short beeps — Minor errors detected. The monitor screen prompts you to enter the CMOS Setup Utility program to correct the situation. Check the reliability of the fastening of the cables in the connectors of the hard drive and the motherboard.

- 3 long beeps - Keyboard controller error. Restart your computer. The motherboard may need to be replaced.

- 1 long + 1 short beeps - Problems with RAM detected. Check if the memory modules are installed correctly. Or replace with other memory modules.

1 long + 2 short beeps - Video card problem - the most common malfunction. It is recommended to remove the board and reinsert it. Also check the connection to the monitor video card.

1 long + 3 short beeps - Keyboard initialization error. Check the connection between the keyboard and the connector on the motherboard.

1 long + 9 short beeps - Error while reading data from the permanent memory chip. Reboot the computer or reflash the contents of the chip (if this mode is supported).

1 long repeated beep - Incorrect installation of memory modules. Try removing and inserting them again.

1 short repetitive signal - Problems with the power supply. Try to remove the dust accumulated in it.

AMI BIOS

No Signals - Faulty or not connected to the motherboard power supply.

1 short beep - No errors found. The computer is ready to go.

2 short beeps - RAM parity error. Restart your computer. Check the memory module installation. The memory modules may need to be replaced.

3 short beeps - Error during operation of the main memory (first 64 KB). Restart your computer. Check the installation of memory modules in the slots. The memory modules may need to be replaced.

4 short beeps - The system timer is faulty. The motherboard may need to be replaced.

5 short beeps - Faulty CPU. The processor may need to be replaced.

6 short beeps - The keyboard controller is faulty. Check the quality of the connection of the latter with the connector on the motherboard. Try replacing the keyboard. If this does not help, then the motherboard may need to be replaced.

7 short beeps - The motherboard is faulty.

8 short beeps - Problems with the video card.

9 short beeps - BIOS chip checksum error. A corresponding message may appear on the monitor screen. Either the chip needs to be replaced or its contents rewritten (if it is Flash memory).

10 short - Unable to write to CMOS memory. The CMOS chip or motherboard needs to be replaced.

11 short beeps - External cache is faulty. The cache modules need to be replaced.

1 long + 2 short beeps - The video card is faulty. Check the connection of the monitor to the connector on the video card. The video card may need to be replaced.

It is quite familiar to many users to hear a beep from the system unit when the computer is turned on. A single short signal indicates that "everything is in order." And if, for example, 1 long signal or a series of sounds sounds instead of it, then it immediately becomes clear that there is a problem. This emits signals to the BIOS, the same program that runs first and tests all components of the computer (from the CPU to the monitor).

The BIOS emits signals during the initial testing of the components of the system unit, while the video card has not yet been initialized, which can display certain text and tabular data on the monitor. With the help of them, you can determine the faulty unit inside the system unit or identify poor contact of external connections.

BIOS errors are encoded into a specific combination of long and short beeps. Moreover, all of them are the same for motherboards of different years of production from almost all manufacturers (from the most famous to "noname"). BIOS audio error codes have a detailed description in the instructions for the motherboard, however, often in English.

The BIOS can make sounds on a mandatory condition: a small, as it is called, system speaker must be connected to the motherboard. Otherwise, BIOS errors will go unnoticed and the user will see only a dark monitor screen.

Sound signals: what is needed to decipher them?

If a single BIOS signal indicates a normal computer startup, then a series of the same short or long sounds (combinations of them) indicates the detection of problems, moreover, of a hardware nature. Then you have to open the cover of the system unit. And even if the user does not interfere with the PC device himself, for example, due to the presence of factory seals on the screws of the cover, decoding these signals will help determine the source of the problem.

Different computer manufacturers may have different beep sounds due to the fact that they use different BIOS versions. Nevertheless, among them you can find those that are typical and most commonly used.

Diagnostics using BIOS sound signals is one of the most effective methods, without the use of special test boards (such as POST-card), therefore, despite the systematic development of production technologies, all motherboards come with a small speaker or, at least, with a connector for its connections.

Sound signals are emitted in the presence of a working power supply and speaker. If they are faulty, then no diagnostics will work. A speaker malfunction can only be determined by replacing it with a known-good copy, which is not always available.

When everything works as intended, then in order to decrypt error codes, you should use a special list that indicates the typical signals for this BIOS version.

Award BIOS beep codes

The most common among the numerous BIOS versions are the versions from the Award developer, who has been making his programs for motherboards since the days when the Pentium trademark did not even exist.

The list of typical signals that are the same for all versions of the Award BIOS is as follows:

Continuous signal. Breakdown in the power supply. The easiest way to check if this is the case is by replacing the power supply with a known-good copy.
2 short. The BIOS pays attention to minor errors, which, nevertheless, require the correct parameters to be entered, for example, by loading standard factory settings.
3 long. The problem is in the keyboard block on the motherboard. The cause can be either a short circuit in the keyboard or connecting cable, or in the motherboard (connector, electronics, electrically conductive dust, etc.).
1 long, 1 short. BIOS errors cause RAM modules. The easiest way to fix the problem is to pull out the modules, blow out the accumulated dust from the connector, clean the contacts on the modules themselves and insert them back into the connector. You can leave only one module for the test period and, if necessary, change them, determining which one causes sound signals.
1 long, 2 short. . For some models of video cards, such codes are issued when there is poor contact in the monitor connector, when at the moment the BIOS is turned on it cannot determine whether there is a connection with it. To fix the problem, you can do with the video card in the same way as with the RAM in the previous paragraph.
1 long, 3 short. The BIOS was unable to initialize the keyboard, which may indicate a malfunction of the keyboard itself, as well as the connector or electronics of the motherboard. The easiest way is to temporarily disable the keyboard, then it will immediately become clear whether it is the source of the problem.
1 long, 9 short. Malfunction of the BIOS chip itself. You should just turn off the computer for a while and try turning it on again. If the situation persists and the BIOS error codes do not change, then you should replace the motherboard or try to flash the chip using a special programmer.
1 long, constantly repeating. Error initializing memory. It is necessary to replace the modules or at least clean the contacts in the connector and try again.
1 short, constantly repeating. Incorrect operation of the power supply. In any case, only a replacement with a serviceable unit or repair of an existing unit will help. Bad contacts are almost never found here due to the large connectors compared to other components of the system unit.

AMI BIOS beep codes

The AMI developer is found in motherboard BIOS less often than its competitor Award, but, nevertheless, he has firmly occupied his own, albeit small, niche in this market, so you should be ready to meet with his audio signal encoding system.

Deciphering the encoding of audio signals:

2 short. The error is caused by incorrect operation of the RAM. In any case, you should start by cleaning the connectors from dust, even if you plan to immediately install new modules to replace the "suspicious" ones.
3 short. Like the previous paragraph, indicates a malfunction of the RAM module.
4 short. The system timer, which is the basis for the operation of all other components of the motherboard, is faulty. The only thing that can be done without replacing it is to turn off the system unit for a while.
5 short. An error occurred while initializing the CPU. You can either turn off the system unit for a while, or remove the cooling system from the processor, pull it out of the socket, and then insert it back. If nothing helps, then you have to change the processor.
6 short. The keyboard or its processing unit on the motherboard is faulty. To clarify the source, you can temporarily disable the keyboard, replace it with a known-good copy.
7 short. Fault in the motherboard. In such a situation, a careful external examination of the board for the presence of contact-closing debris can help.
8 short. Bad video card. You should replace it or, in extreme cases, clean the contacts in the connector. You can temporarily enable the built-in video card and check the operation of the computer with it (if, of course, it is available).
1 long, 2 short. Error while initializing video card. The elimination methods are the same as in the previous paragraph.
1 long, 3 short. Fault in the video card.
1 long, 8 short. The problem is either in the video card or in the monitor.

The following lists of BIOS signals are the basis for diagnosing a computer when there are no other options. In most cases, they allow you to determine the source of the problem, which can simply be replaced with a known-good unit.
