Bios is one long. One long, two short Bios beeps: what to do

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 transcripts sound signals BIOS.

This is how the Phoenix BIOS beeps in a special way

BIOS Phoenix squeaks a little differently than its brothers. It is more melodic, so to speak in this context. Dotted sound signals from the Phoenix BIOS alternate with pauses between them. And absolutely all signals from that BIOS are always short.

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 on topic, first you need to know what a speaker is and why it is needed.

What is a motherboard speaker?

Motherboard speaker- it's miniature tweeter, warning the user about malfunctions in the operation of your computer even before turning it 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 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 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».

A fairly common situation is the problem when, when turning on the computer, the user hears one long and two long sounds from the system speaker. short beeps BIOS. In this case, loading operating system is not performed at all, and the user sees a black screen in front of him (sometimes messages indicating a problem may appear, but, as a rule, they are absent). Read on to learn how to interpret this sequence of signals and what to do to correct the situation.

One long, two short BIOS beeps: what does this mean?

Let's start with theoretical information. When you turn on your desktop computer or laptop, all hardware is checked. The primary one is responsible for this. BIOS system(or its modernized version UEFI). For each such system, the use of strictly defined signal sequences is provided, which can indicate either that the test was completed successfully, or that problems were found in the operation or initialization of the equipment. In general, to figure out what the problem is, you need to contact technical documentation primary system or at least read what different sequences and combinations mean.

IN in a general sense, if the user hears one long and two short beeps from the BIOS of ASUS or any other developer of the primary system, we can immediately conclude that something is wrong with the installed hardware. Unfortunately, the system does not provide notifications about faulty components.

The only situation is a message about the absence of a connected keyboard. But this mostly applies exclusively to stationary terminals, since on laptops such a message can only appear if the built-in keyboard has become unusable. Connect any other external keyboard, for example, via USB and check how the system will boot.

One long, two short BIOS beeps: what to do first?

The issuance of such a sequence of signals may not always be associated specifically with physical damage installed equipment. It is quite possible that somewhere on the motherboard the contacts have simply come loose or become clogged. All components may be in perfect order, but dust or contamination of the inside of the computer can lead to the fact that some elements of the filling are simply not detected.

In the simplest case, if you receive one long and two short signals from the BIOS, you should immediately turn off the computer and completely disconnect it from the power supply. After this, you need to pause so that the residual currents disappear (ten minutes will be enough), then remove the side cover of the stationary PC case from the side accessing the motherboard and perform a basic dust removal. A regular vacuum cleaner with the minimum suction power set is suitable for this. When cleaning, you need to be very careful not to damage the components installed on the motherboard and the motherboard itself, or even the whole computer system will stop working. And replacing a motherboard is clearly not a cheap pleasure.

Problems with the graphics chip

Basically, most situations when the user hears one long and two short BIOS beeps are usually attributed to problems with the graphics adapter, since it is the adapter that is responsible for displaying the image on the screen, and if it malfunctions, problems arise with the inability to start the operating system.

IN different versions BIOS (and from different developers) such a sequence of signals may indicate various failures. For example, IBM BIOS issues such signals only if the computer is equipped with Mono/CGA video cards. But since such chips are practically not found today, such situations are very rare.

In the case of AST BIOS, such a sequence is issued only if problems are observed with frame scanning.

Compaq BIOS gives one long and two short beeps if initialization of the graphics adapter is not possible at all. The same situation is observed with the primary systems Award and Quadtel.

The only way to fix the problem is physically. To do this, you need to remove the video card from the corresponding slot on the motherboard and first check its functionality on another computer. If it works as expected, the slot itself may need to be cleaned. You can also try inserting it into a different connector. If the card does not work, it will have to be replaced.

Possible problems with RAM

But problems are not always associated specifically with graphics adapters. For example, AMI BIOS generates one long and two short signals if problems with RAM are detected (for a video card, a sequence of pulses in combination 1-3 is used).

In this case, the memory sticks should be removed one at a time when the power is turned off, turning on the computer after each removal and checking the functionality of the system. When the damaged strip is found and the system boots in normal mode, you will simply have to replace it by installing similar equipment in its place. In this case, you should take into account which generation the RAM belongs to, and also pay attention to the characteristics of the motherboard itself in terms of ensuring that it supports the installed brackets both according to the standard and the maximum volume. Otherwise, you will not be able to use the maximum volume because the defined motherboard may turn out to be much less.

What to do if the problem persists?

But let’s assume that it was not possible to get rid of the malfunctions using such simple methods. Let's take a situation where a similar combination is given by samsung laptop. One long and two short BIOS signals enough to identify problems with the equipment, but disassembling the device yourself is not always advisable.

In some cases, you can do much simpler, since the problem may be incorrect settings of the primary system. To get started, use reset parameters from the appropriate section, save the changes and check how the loading will proceed. If such actions do not produce results, updating the BIOS may very well help. True, such actions must be performed with skill, so as not to render the primary input/output system itself unusable.

A similar solution can be applied to stationary computer terminals. But this situation can mainly be associated with the replacement of equipment or the installation of new components, when outdated version BIOS appears unable to recognize modern devices. IN in this case firmware update is the best option fix the problem.

Instead of an afterword

It remains to add that the situation when a sequence in the form of one long and two short BIOS signals is output through the system speaker can, in principle, be corrected. Since the real reason Such behavior of the system is not explicitly indicated; you will have to perform the described actions exactly in the order in which they were given in the above material. It is advisable not to use reset and update immediately, but leave them as a last resort if methods of physical intervention are powerless. However, first, clean the stationary unit from dust. This is the first remedy. With laptops the situation is more complicated, especially if the device is under warranty. If none of the above suggestions help, you will have to contact an authorized service center. And avoid contacting private contractors who do not have relevant repair experience. computer equipment. Then many more problems may appear.

In addition to the visual error codes that we see with our eyes, there are others - BIOS sound signals.
A little theory.

On any motherboard, be it a computer or laptop, there is a special memory chip. It contains program code, or as it is fashionable to say now - microprogram. It is called BIOS (BIOS - Based Input-Output System).

You turn on the computer and the first thing that starts to load into the RAM is not the operating system, but the BIOS. If everything is in order, we hear one short beep and the computer begins the POST procedure, i.e. checks the functionality of your PC components one by one.

But then a failure occurs, and you hear three short BIOS beeps. There is no image on the monitor. Yeah.. An experienced technician will immediately check the RAM modules - they are dusty or one of them is out of order. But there are several manufacturers of firmware and, accordingly, each of them has its own BIOS signals.

Below, we present most of the standard BIOS codes from various manufacturers. In the third column of each table, “Actions,” there will be short explanatory comments—like “sidenotes.”

Attention! Everything written below is for informational purposes only. All error transcripts are taken from authoritative sources. Everything in the “Actions” column is advisory in nature. All your actions are carried out by you based on your own decisions. Only you and no one else will be responsible for damaged equipment. That is why, be reasonable, correctly assess your strengths and knowledge, and in case of the slightest doubt, ask for help from specialists.

Before deciphering BIOS sounds, you must determine which manufacturer's firmware is installed on the motherboard.

The most interesting thing is that many sites suggest going into the BIOS itself in order to find out who the manufacturer is. In a large percentage of cases, if you come across an article like this, it means you hear beeps of BIOS errors, but do not see anything on the monitor. It is logical to assume that you cannot get into the firmware.

Therefore, we can only help you remember what BIOS you have by showing screenshots. Unfortunately, the firmware of even one manufacturer can look almost the same as that of another.

AMI BIOS Signals (American Megatrends Inc.)

AWARD BIOS

We have provided tables of BIOS sound signals for three main types. The tables show actions that can be taken when a particular error signal appears. As you may have noticed, many fields are empty. You can help us fill them out or supplement existing ones. Write in the comments if the problem was resolved in any way not listed here.

The topic of this article will be BIOS. First, we will deal with the question, what is BIOS and what does it serve? And then we will describe the BIOS sound signals in as much detail as possible.

BIOS (Basic Input-Output System, basic system input-output) is a special program that is stored in a ROM (read-only memory) chip. The English designation for this type of memory is often found – Read Only Memory, or ROM for short. In practice already for a long time Instead of conventional ROM chips, they use Flash memory, which is rewritable, which allows the user to independently update BIOS versions.

BIOS Features

Regarding BIOS functions, then they are very extensive.

Firstly, as soon as the PC’s power is turned on, control immediately passes to the BIOS. This program performs initial testing of system unit components. After a successful check, the BIOS transfers control of the computer to the next program, which is written to the Boot sector (boot sector) located on the boot disk (as boot disk can act hard drive, CD, floppy disk, flash drive, etc.). The initial testing procedure for equipment is called POST (Power-On). Self Test– self-test after turning on the power).

Secondly, thanks to BIOS, the computer's hardware configuration is stored in a special CMOS chip. When the PC is powered on, the current hardware configuration is compared with the one stored in the chip. If the program finds differences between these two configurations, then the CMOS memory data will be updated and, if necessary, you will be prompted to go to BIOS Setup to specify the new parameters of the detected hardware. If differences in configurations are not detected, or the configuration update can be performed without user intervention, then the program carries out the necessary settings (configuration) of the computer’s hardware components.

CMOS memory (Complementary Metal Oxide Semiconductor) is a small RAM chip (RAM or RAM - Random Access Memory). But since there is a need to retain information in it even after the power is turned off, the CMOS memory is additionally powered by its own battery. This battery itself is associated with several problems. One of them is a limited service life, which is 5-6 years. After this period of time has passed, the battery can no longer provide the required level of power, which leads to the loss of stored information in the chip. Although this problem can be solved quite simply - install a new battery.

Thirdly, with the help of special BIOS programs Setup the user can set various parameters and select operating modes for individual PC components. Here the user can disable equipment that is not in use or its use is undesirable in order to ensure computer security. Fourthly, when BIOS help I/O operations are processed. This is actually why this system was originally developed. Thanks to the presence of BIOS, for example, the hard drive understands that the head needs to be placed on a specific track or read a certain sector, etc.

If all programs had to contain instructions of this kind, then they would be huge in size, and their work would be very inefficient. In addition, with the advent of each new device they would have to be modified. Therefore, in order to avoid such problems, a significant part of the work associated with processing I/O operations was assigned to the BIOS. Naturally, BIOS operation did not solve absolutely all problems, but significantly simplified the solution to most of them. It is worth noting that today this is no longer as relevant as in the days of the operating room. MS-DOS systems. Modern operating systems such as Windows XP, Windows Vista or Windows Seven make little or no use of the BIOS's I/O capabilities. But here it must be said that everything said is very conditional. In fact, all tasks are performed by the operating system in close interaction with the BIOS, complementing each other functionally.

The average user more often has to deal with that part of the BIOS called BIOS Setup. BIOS Setup is a special subroutine that allows you to configure the operation of individual computer hardware components. The main difficulty in setting it up lies in the unclear names of the options, which can tell little to a less advanced user. In addition, the problem is exacerbated by the lack of reference material for these settings. But if we look at it as a whole, BIOS Setup is nothing special; the only thing that sets it apart from other programs is its rather archaic interface compared to modern operating systems. All settings made by the user while setting up the computer via BIOS Setup are saved to the CMOS memory chip, where they are stored along with data about the system’s hardware configuration.

How to reset BIOS settings

Below we will give several methods that help solve problems with resetting the BIOS, that is, returning it to original state, in which all settings will be as they were before the user made changes. Often, such a simple operation as resetting the BIOS settings allows you to eliminate a number of problems with starting your computer, and also helps to avoid visiting a service center.

Method 1

We return the BIOS to the factory default settings using the interface BIOS setup, which will allow us not to disassemble the system unit once again. It should be noted that this method feasible in cases where the BIOS is loading. To reset the BIOS, you need to find the load bios defaults or load setup defaults item in the menu, as shown in the figure and press Enter.

Method 2

Reset BIOS settings using a battery. Before you begin, you should completely disconnect power from your computer. After you make sure that all cords are removed from the sockets, you need to remove the side cover of the system unit. Next, find the same battery and remove it for 5-10 minutes. After this period, you can return it to its place. The BIOS should be reset.

Method 3

Reset the BIOS settings using a jumper (jumper). Finding a jumper on the motherboard is easy; it is almost always located next to the battery. It is designated as Clear CMOS or Clear RTS. Sometimes motherboard manufacturers place it near the edge of the board to make it easier to access. To reset the BIOS settings, you need to move the jumper for a few seconds from position 1-2 to position 2-3, and then return it to its place.

If everything is done correctly, then after turning on the computer, after a few seconds one short signal will be heard - this indicates that the system is in order and the operating system will then begin loading. If hardware problems are detected in the system, the signal will have a different appearance. By the type of signal, you can determine what kind of malfunction is detected, and what further actions should be undertaken. All BIOS signals (supplied using a speaker) are distinguished depending on its version and, of course, depending on the nature of the detected malfunction. The BIOS version is determined based on the documentation that comes with the motherboard. If the documents are missing for some reason, then you can determine the BIOS version using special utilities, which are available in abundance on the Internet. Another BIOS version is usually displayed on the monitor screen when the computer starts in the lower left corner. Of all the BIOS manufacturers on the market, two main competitors should be highlighted: software which the vast majority of modern PCs are equipped with. These are two well-known brands such as American Megatrends(AMI) and Award Software. So, first let's look at the AMI audio alarm.

BIOS beeps: AMI BIOS

• – Two short beeps from the speaker indicate some kind of malfunction in the computer’s RAM. Troubleshooting options: you need to remove the memory module from the slot, wipe it with a dry brush and insert the module into place; if after starting the PC the signals repeat, then further testing of the memory or its complete replacement may be required;
• – Three consecutive short beeps from the speaker indicate an error in reading the first 64 KB of PC main memory. Troubleshooting options: it is necessary to remove the memory module from the slot, if there is dust, wipe the strip with a dry brush and insert the module into place; if the signals repeat, further testing of the memory or its complete replacement may be required;

• – Four consecutive short beeps from the speaker indicate a system timer malfunction. Troubleshooting options: restart the PC again, and if the signals repeat, then repair or replace motherboard;
• – Five consecutive short beeps from the speaker indicate a malfunction of the central processor. Options for troubleshooting: reboot the PC again, if the signals repeat, replace the processor;
• – Six consecutive short beeps from the speaker indicate a malfunction of the keyboard controller. Troubleshooting options: Check the cable and connection of the keyboard to system unit, check the keyboards on another computer. If after checking it turns out that the keyboard is working, then the only option left is to repair the motherboard or replace it;
• – Seven consecutive short beeps from the speaker indicate a malfunction of the motherboard. Troubleshooting options: reboot again and if the signals repeat, then repair or purchase of a new motherboard will be required;
• – Eight consecutive short beeps from the speaker indicate a memory failure graphics card. Troubleshooting options: if the signals repeat after a reboot, you will need to either repair the old one or purchase new video card;
• – Nine short beeps in a row indicate a malfunction of the BIOS chips. Options for troubleshooting: flashing the microcircuit or replacing it completely;
• – Ten consecutive short beeps from the speaker indicate the impossibility of writing to the CMOS memory. Troubleshooting options: clearing the CMOS memory using one of the above options. If the signals repeat after setting the BIOS default values, the CMOS memory module must be replaced;
• – Eleven short beeps in a row from the speaker indicate a faulty RAM. Troubleshooting options: it is necessary to remove the memory module from the slot, if there is dust, wipe the strip with a dry brush and insert the module into place; if the signals repeat, further testing of the memory or its complete replacement may be required;
• – One long and three short beeps from the speaker as well as one long and eight short beeps again indicate a faulty video card. The troubleshooting options are the same as in the previous case.
• – The absence of speaker signals may indicate a faulty power supply. Troubleshooting options: check the fastening of the power supply plugs to the connectors on the motherboard, clean the power supply from dust. If these steps do not produce results, if possible, try to test the power supply on another computer. If such symptoms occur, you will need to either repair it or purchase a new power supply.

BIOS beeps: Award BIOS

• – One short beep from the speaker means there are no errors in the system and the computer is in fully working order;
• – Two consecutive short beeps from the speaker indicate the detection of “minor” errors. Troubleshooting options: you need to check that the components and cables are securely attached to the PC motherboard, then try to set the BIOS to default values;

• – A short, repeating speaker signal indicates a faulty power supply. Troubleshooting options: check the fastening of the power supply plugs to the connectors on the motherboard, clean the power supply from dust. If these steps do not produce results, if possible, try to test the power supply on another computer. If such symptoms occur, you will need to either repair it or purchase a new power supply;
• – A long, repeating beep from the speaker indicates a RAM problem. Troubleshooting options: it is necessary to remove the memory module from the slot, if there is dust, wipe the strip with a dry brush and insert the module into place; if the signals repeat, further testing of the memory or its complete replacement may be required;
• - Three long signal speaker indicates a faulty keyboard controller. Troubleshooting options: check the cable and connection of the keyboard to the system unit, check the keyboards on another computer. If after checking it turns out that the keyboard is working, then the only option left is to repair the motherboard or replace it;
• – One long and one short beep from the speaker indicates a faulty RAM. Troubleshooting options: it is necessary to remove the memory module from the slot, if there is dust, wipe the strip with a dry brush and insert the module into place; if the signals repeat, further testing of the memory or its complete replacement may be required;
• – One long and two short beeps from the speaker indicate a faulty video card. Troubleshooting options: you need to check the cable going from the video card to the monitor, if the cable is OK, you need to remove the video card from the slot, wipe it off dust, if necessary, and insert it back. If these actions do not produce results, then you may need to repair or purchase a new video card;
• – One long and three short beeps from the speaker indicate a fault with the keyboard controller. Troubleshooting options: check the cable and connection of the keyboard to the system unit, check the keyboards on another computer. If after checking it turns out that the keyboard is working, then the only option left is to repair the motherboard or replace it;
• – One long and nine consecutive short beeps from the speaker indicate a malfunction of the BIOS chip itself. Options for troubleshooting: flashing the microcircuit or replacing it completely;
• – The absence of speaker signals may indicate a faulty power supply. Troubleshooting options: check the fastening of the power supply plugs to the connectors on the motherboard, 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 is necessary to note the continuous BIOS sound signals that change in tone. This can be caused either by a faulty power supply or an overheating PC.

Computer crashes and errors

Compared to audio signals from other manufacturers BIOS sound BIOS AMI signals are very diverse. In most cases, these beeps allow you to identify a malfunction during the computer boot stage and the POST hardware test procedure. Typically, all you need to do to determine which component is causing the problem is to count the number of beeps emitted by the system speaker.

Below are the beeps produced by the BIOS AMI. In all cases, the number of signals and their type (long/short) are indicated.

• No signals

This situation is perhaps the most unpleasant that a user can encounter. As a rule, it means that power is not supplied to the motherboard or the BIOS is generally faulty. No power to the motherboard usually means either a faulty/broken power cable or a faulty computer power supply.

• One short

A single short signal is the same signal that all users are accustomed to hearing every time they start their PC. It means that no errors or problems were detected during the hardware check, and the computer can continue to boot.

• Long continuous

This signal means that the PC power supply is faulty. However, unlike the situation with a complete absence of signals, in this case power is supplied to the motherboard, but its parameters do not correspond to the nominal value.

• Two short

This signal indicates an error in the RAM. This error may indicate either a malfunction of the memory modules themselves, or simply that one of the modules is poorly inserted into the slot.

• Three short

This type of signal also indicates an error in the RAM. But this error is quite specific and rarely encountered - it is an error in the first 64 KB of RAM.

• Four short

This signal indicates a malfunction of the system timer. Fortunately, this type of malfunction occurs infrequently, but it is not uncommon the only way The solution is to replace the entire motherboard.

• Five short

Similarly, the BIOS informs the user about a heart failure personal computer– central processor. However, this malfunction may not always be associated with a defect in the processor chip itself. Often, to fix the problem, it is enough to check that the processor is securely installed in the socket.

• Six short

This message indicates a problem with the keyboard controller or that the keyboard itself is missing. Very often, to correct this situation, it is enough to check the contact in the keyboard connector on the system unit.

• Seven short

Such a set of sounds indicates a rather serious malfunction - namely, a failure of the system board. However, sometimes the error may disappear after checking the power cable contacts on the motherboard.

• Eight short

BIOS message indicating video memory failure. But here, as with many other errors, sometimes the problem may simply be poor contact - in this case, between the motherboard slot and the video card.

• Nine short

In this case, the BIOS signals a checksum error. BIOS memory. The reasons for this phenomenon may be different - an error in new version BIOS or random crash in CMOS memory. Often the problem can be fixed by flashing the BIOS.

• Ten short

With this set of signals, the BIOS reports an error in writing to CMOS memory. As a rule, this error is more serious than the previous one and often requires the intervention of a specialist from a service workshop.

• Eleven short

• One long, then two, three or eight short

This type information message tells the user that there are video card errors. Typically, such sound signals are only generated when using old video cards (Mono/CGA/EGA), so the chance of encountering them is currently extremely small. In most cases, this malfunction can be eliminated by carefully installing the video card in the connector.
