Bius transcript. BIOS beeps when turning on the computer
Many people know that when you start a computer, the BIOS is first loaded, which immediately scans and checks all devices for serviceability and ability to function normally. BIOS when loading Windows are a consequence of the fact that some kind of error has been detected in the system.
Of course, it is almost impossible to remember all of them, so you should always have the instructions in front of your eyes. Or, for example, print this article and use it in the future.
It is worth noting that BIOSes differ from different manufacturers, and, accordingly, too.
For reference, I would like to say, how you can determine the BIOS brand so that you know, just in case something happens, and can correctly identify the initialization error. The name is visible when loading the PC, or using some programs, for example, Everest (Aida).
Let's start with the oldies. I don’t think it’s worth describing all possible signal options, but it’s worth mentioning only the most basic and frequently occurring ones.
1 short:
Blank screen and 1 signal: The video system is faulty and therefore no information is displayed on the screen.
2 short: monitor is not connected.
problems detected with motherboard.
If
A short signal that either repeats periodically or is simply continuous: any failures or defects motherboard or BP.
If there is no signal at all, then this means that you have a motherboard or a power supply.
SignalsAMI BIOS:
1 short: POST completed successfully. That is, no errors were found.
1 long and then 1 short: Some problems were discovered with the power supply.
1 long and then 4 short: video card not detected.
2 short: The printer or scanner is turned on.
3 long beeps: RAM problems. Try reinstalling it or replacing the rulers.
4 short: The system timer has failed.
5 short: Some problems have been detected with the processor.
7 short: at mat. problems have been detected on the board.
8 short: The video card memory generated an error.
1 long and then 2 short: the video card has some problems (Mono / CGA)
If 1 long and then 3 short: the video card has some problems (EGA / VGA)
1 long and then 8 short: There is no monitor or the video card is faulty.
Blank screen and no signal: the processor has failed, or bad contact at his feet.
The signal is continuous: The power supply is faulty or the computer is overheating
BIOS signals from Award:
1 short: POST completed successfully. No flaws found.
2 short sounds: Only minor interference was detected. It will be necessary to check the contacts and various fastenings of the cables, hard drives, etc.
3 long: an error caused by the controller for working with the keyboard.
1 short and then 1 long: error reading or writing information from RAM.
1 long and then 2 short: Video card errors detected.
1 long and then 3 short: error reading or writing information from video memory.
1 long and then 3 short: error reading or writing data from ROM.
A short signal that repeats periodically: Some defects were detected in the power supply.
A long signal that repeats periodically: Problems with RAM.
Repeated beep, sometimes at high, sometimes at low low frequencies: Problems with the processor.
Continuous signal: Malfunctions in the power supply.
And lastly... If you have some other version of BIOS, or you want to find out all the sound ones, then go to the manufacturer’s website and look at the instructions. If you don't find detailed instructions on similar sites, then try looking for more detailed information on the links that are provided in the Everest program.
Sound BIOS signals are among those things the knowledge of which will never be superfluous for a PC user. Why are they needed, in what cases are they used, how do sounds differ in different versions BIOS and what to do if the computer “beeps” differently than usual? We will try to understand these issues in this article.
One of the functions of the BIOS, as a hardware and software complex that links together all the components of a computer, is testing the equipment included in the computer. This check is carried out immediately after turning on the computer and is called POST. POST includes a number of tests hardware and checking the functionality of all computer components. If the check is successful, the BIOS transfers control to the operating system (of course, if the computer is equipped with it at all). And if the check reveals any malfunction, the BIOS usually displays a message about the nature of the error encountered. If it is serious, then the computer and loading of the operating system become impossible.
In some cases, errors can be so serious that the computer will be unable to even turn on the video system and display a message about the type of error on the monitor screen. It is for such cases that almost all BIOS provide a system sound notification user about the nature of the error found during the testing procedure. Thus, having heard that the computer “beeps” and determined the sequence of sound messages it produces, the user will be able to recognize the type of error by ear, even without looking at the monitor screen. But, of course, only if the user remembers by heart or has before his eyes a list of BIOS signal symbols.
Types of BIOS beeps
Unfortunately, since BIOSes are produced by different manufacturers, audio messages, published different BIOS, are not universal, and their codes may differ significantly from each other. Therefore, each user needs to know the signal codes corresponding to the BIOS installed on the motherboard of his particular computer.
Over the entire existence of personal computers, their BIOSes have been developed by many companies, but the systems of the following companies have become the most common: American Megatrends(AMI), Award and Phoenix. Accordingly, most often the user may encounter the following sets of sound signals:
For each BIOS option There is a table that provides a breakdown of BIOS error signals. Deciphering signals successfully usually requires careful counting of how many times the computer beeps, and if you miss a single beep, it can cause the decoding to fail and have to start over.
Some features of BIOS beeps
A set of signals may consist of sounds various types. Based on their duration, computer BIOS sound signals are divided into short and long. Also, in some cases, the BIOS may emit one continuous beep.
Typically, BIOS signals are produced by the system board's built-in speaker. Some BIOSes also have the ability to output audio signals from the computer's motherboard through speakers connected to the audio line-out port.
As mentioned above, all BIOS manufacturers use their own own system sound signals, and in most cases these systems are not the same. However, almost all BIOS (with the exception of AST BIOS) have a signal that is decrypted in the same way. If the system speaker beeps once, this means that the POST procedure has completed successfully and the PC can continue to operate.
Some BIOS can send a single short beep to two addresses at once: one to the system speaker, the other to an external speaker connected to the audio output. In this case, a single squeak can sometimes sound like a series of two signals. You should be aware of this feature so as not to confuse this sound with a real double beep that is emitted if POST detects any errors.
The absence of any signals usually means that the BIOS is not working, which in turn could be caused by a faulty motherboard or power supply. However, do not forget that often this situation is just a consequence of a malfunction or absence of the system speaker. If you boot you hear how it works system unit, and you see that the usual messages are displayed on the monitor, but do not hear a squeak emitted by the speaker, then, most likely, this is the case.
If you hear a series of beeps indicating an error, but the computer continues to boot (in some cases it may continue after pressing a certain key), then this means that the nature of the error is not so serious that it would be impossible to computer functioning. However, your computer's performance may be limited in this case, and you should make an effort to understand the situation causing the error and take steps to resolve it. In many cases, the problem can be easily fixed on your own, but sometimes there is nothing left to do but replace the non-functioning computer components.
Conclusion
BIOS sounds are information messages of a special kind, supplied through the system speaker of the motherboard and occurring during the POST procedure. Based on the number and shape of BIOS signals, these messages are decrypted, and as a result, the user can judge whether the POST procedure was successful, and whether any error was detected during it, and if so, determine the type of this error. Various errors have corresponding sound codes. In most cases, these codes are unique to each BIOS manufacturer.
An attentive user may notice that the computer makes sounds when turned on. Usually this is one short squeak from the speaker (device on the motherboard). But during operation, other signals may be emitted. Read about what they mean and how to find out what to do with them in this article.
The first thing you need to do is 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. Look at the top or bottom of the abbreviations AMI or AWARD BIOS.

Now you know about BIOS sounds and how to decipher them.
Greetings, friends! Today I will tell you about BIOS sound signals. You may have noticed that when you turn on your computer, it makes a beeping sound or, in other words, beeps. This actually beeps your computer's BIOS, thereby telling you whether everything is fine with your computer or if there is any problem. Let's try to understand this topic in as much detail as possible.
What do the BIOS beeps mean when you turn on your computer?
Whatever BIOS is installed on your motherboard, you should hear one short beep when you turn on your PC. This means that everything is working fine and after it will start Windows boot. However, sometimes the opposite is true. The BIOS beeps like crazy, and the computer either doesn’t turn on at all, or the startup 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 sound signals.

| 1 short | Everything works fine. Don't pay any attention to him. |
| 2 short | The RAM is not working properly or is faulty. Try disassembling the system unit, removing the RAM from the slots and inserting it back. Perhaps this will solve the problem. Otherwise, you will have to contact a service center or buy new RAM. |
| 3 short | Almost the same as 2 short beeps. Do the same as in the previous paragraph. |
| 4 short | There is something wrong with the system timer on your motherboard. Try resetting the BIOS to factory settings. If that doesn't help, try replacing the battery, it's inexpensive. |
| 5 short | One of the worst mistakes. Your central processor is faulty. A simple reboot 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 have to either replace the keyboard or repair the connector on the motherboard. |
| 7 short | This is also scary. The motherboard is faulty. And it would seem that 7 is a lucky number. Such a surprise. |
| 8 short | Transmitter your video card. Although, try pulling it out and inserting it back into the slot, maybe this 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 wouldn’t recommend it, if they fix it, it won’t be for long. |
| 9 short | You need to update or flash the BIOS of your computer. |
| 10 short | Error in operation CMOS memory. Take it to the service center, they will help you. |

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 know, first you need to know what a speaker is and why it is needed.
What is a motherboard speaker?
Motherboard speaker is a miniature high-frequency speaker that warns the user about malfunctions in the operation of your computer even before it is turned on. In other words, a speaker is a means of displaying information about the state of the computer. Also, a speaker is a device that produces BIOS sound signals!
This is what the speaker looks like on the motherboard. It is he who helps emit BIOS signals!
Some reasons why your PC may not beep at startup
It often happens that manufacturers budget computers(and not only budget ones) either forget to install the 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 your friend's speaker for the 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 your computer is that you accidentally touched it or pulled it, and it just became a little disconnected. In this case, insert it more tightly and everything will beep. By the way, there are also motherboards in which the speaker is not disconnected at all.
The BIOS does not beep on laptops, because they do not install a speaker on them for aesthetic reasons. Imagine if every time you turned on your laptop, it gave you a characteristic, high-frequency signal. It's annoying.
Especially if your wife has already fallen asleep, and you decide to play tanks in secret, you turn on the laptop, and here you are wearing BIIIIIIIP!!! Your wife immediately woke up and hit you with a star. In general, the speaker is not so relevant on a laptop.
Although some laptops can produce similar audio signals through external speakers and even headphones. Everyone who encounters this is trying to get rid of this squeak (pipiska) as soon as possible by any means.
Where and how to connect the speaker on the motherboard?
This will be useful for you to know if you decide to borrow the missing speaker from a friend or buy it. When you removed the speaker from a friend’s motherboard, you should have noticed that the place where it is connected is marked with characteristic inscriptions, most often it appears there Speaker or spk or spkr. The polarity of the speaker does not matter, so you can connect the speaker without error.
Several examples of motherboards with designated places for connecting a speaker.
Let's summarize
The article turned out to be quite lengthy, 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 it is needed. We also looked at the decoding of sound signals for the main and most popular BIOS versions. If your BIOS version differs from those considered, then simply specify your request in a search engine, for example “ decoding BIOS sound signals IBM/DELL».

Many motherboards come with built-in system speaker on board. When you turn on the computer, one short signal usually sounds, which indicates that there are no errors, as a result of which the equipment continues to operate and boots operating system. The sound signal becomes an integral part of the successful startup of the PC and after a while the user simply stops noticing it.
But, unfortunately, it may happen that when you turn on the computer, a non-standard signal will be heard or it will be completely absent. This may indicate either partial or complete PC malfunction due to problems in various equipment. In order for the user to find out exactly where the problem occurred, BIOS technical signals are provided, which will help identify the malfunction of a specific computer module.
What is BIOS
Before moving on to considering the features of certain types of BIOS, it is worth telling what they are in general. Basic Input Output System is a program written on a chip located on the motherboard itself.
The BIOS is responsible for all low-level hardware settings. Without it, the computer simply will not know the principle of its operation: where to boot from, what functions of the motherboard need to be activated, what the rotation speed of the coolers should be, and much more.
BIOS tasks and functions
- At the very beginning of booting the computer with basic software The CMOS is checked for user settings.
- Interrupt handlers and device drivers are loaded.
- The registers and power management are initialized, as well as self-testing when power is applied.
- After this, the screen displays system settings and bootable devices are determined.
- The final stage of preparing the equipment for loading the system is the initialization of the bootstrap program.
AMI BIOS
The abbreviation AMI comes from the name of the company American Megatrends Incorporated, which is the owner of this development.
The main menu is presented with a convenient list of settings in two columns.
On this settings tab you can change system date, and also select the order of boot devices.
Depending on the company specific model and versions BIOS location items may be slightly different. The AMI BIOS menu is quite simple, and it will be difficult to get lost in it. Detailed information The locations of menu items and settings can be found on the manufacturer's website or in the documentation that came with your motherboard.
AMI signals
The developments of each BIOS manufacturer have their own unique system alerts, which will help determine the malfunction. Below are the sound signals ami bios with a description of the problems and their possible solutions.
Designations in the table:
- "To" - short signals BIOS;
- "d" - long signals BIOS.

|
The problem is related to the video adapter. You need to remove and reinstall the video card into the slot. If the error recurs, it may need to be replaced. |
|
It is worth remembering that in this type of BIOS there are no long signals at all, thereby complicating the task of identifying errors. In most cases, solving problems related to RAM, is to check and replace faulty modules one by one. For a more detailed check of the computer for errors, POST cards are used, which can provide comprehensive information about faults.
Modern BIOS replacement
Nowadays it is becoming increasingly popular UEFI system, replacing the usual BIOS. It has a clearer graphical interface with mouse support and has many advantages, some of which are increased loading speed, support for new hardware, and new data protection methods.
