Reset BIOS settings possible in three ways:

Note: BIOS models vary and therefore your BIOS may look different.

In the window that appears warning that the settings will be reset, select YES.

All BIOS settings are reset.

Reset BIOS settings. Method 2

Every computer has a battery () that constantly supplies voltage in order for the computer to BIOS settings were not reset.

What to do:

1. Turn off your computer.

2. Disconnect the computer's power cord.

3. Remove the cover of the system unit.

4. Remove the BIOS battery.

5. Close the “+” and “-” contacts of the battery socket.

6. Wait 10 minutes.

7. Reinsert the battery.

8. Collect system unit computer.

9. Connect all wires.

10. Turn on the computer.

Bios settings have been reset.

How to reset bios. Method 3

Some motherboards have a special jumper that can be used to reset the BIOS settings. Called a jumper CLEAR_CMOS (reset BIOS). It is located next to the BIOS battery:

In order to reset the BIOS settings, you need to move the jumper to the position 1-2 :

Then wait 10 seconds and return the jumper back to position 2-3 .

Incorrect BIOS settings can completely stop your computer. You can correct the situation by rolling back the settings to factory settings. This function is provided on all PCs, but the reset method differs depending on the device used.

When a factory reset is required

Fortunately, the need to completely reset settings does not arise very often. Typically, the user can manually change the configurations to return the device to a working state. The following describes cases in which, without full reset parameters are indispensable:

  • I can't remember the OS or BIOS password. In the first case, specialized programs or reinstalling the system can help, and in the second, only rolling back the settings.
  • Errors when loading the system or BIOS. Failures are not always caused by incorrect settings, but in some situations, restoring default settings helps solve the problem.
  • Incorrect BIOS parameters specified by the user when there is no way to manually restore the original settings.

Method 1: Special Applications

Computers based on 32-bit Windows have a built-in tool with which you can roll back the settings to factory settings. This method is only suitable if it is possible to log into the OS.


Please note that the method is only suitable for 32-bit Windows. This method may not always help in restoring parameters, so it should be used only as a last resort.

Method 2: CMOS battery

Almost all motherboards are equipped with a CMOS battery. This element is responsible for storing BIOS data. If you remove the component, the parameters will be automatically reset. Be careful, not all boards provide the ability to remove the battery.


Method 3: Jumper

Modern motherboards are often equipped with a special jumper, by moving which you can reset the BIOS settings. This is done this way:


Sometimes there are boards with more than 3 contacts, in this case, focus on the names “CLRTC” and “CCMOST”. These are the necessary contacts.

Method 4: Special button on the board

Unfortunately, not all motherboards have a button that is responsible for resetting parameters. It can be located both inside the device body and outside. Usually the button is named “clr CMOS” and is highlighted in red, but this is optional. It is better to start your search from the back panel of the computer, where the connectors for connecting components are located. When you press the button, the BIOS settings will be restored to factory settings.


Method 5: Through BIOS

You can also reset the settings using the interface itself. This is a more convenient method than the previous ones, since there is no need to disassemble the device case. It is recommended to use this method only experienced users, as there is a possibility of seriously aggravating the problem with the computer.

The method for rolling back settings may vary slightly depending on the BIOS version and PC settings.


Resetting the settings to factory settings yourself is not as difficult as it might seem at first glance. You must be extremely careful and strictly follow the recommendations in the article so as not to cause even more harm to the device.

Sometimes a novice user does not understand how serious the consequences of incorrectly made changes to the operation of the basic input/output system can be. However, not all users who are able to enter the “holy of holies” of a computer system know how to reset the BIOS settings. But sometimes it happens that the user urgently needs to return computer technology“stability parameters” lost for one reason or another. Therefore, let's look at all the known and most used methods of resetting BIOS settings to their original state.

It is extremely important for a novice user to know how to reset BIOS settings!

And this is true! Unforeseen situations when it may be necessary to carry out such a software and hardware procedure are, as they say, a big cart. The most common problem - the inability to boot into the OS - is often the result of incorrectly made changes to the BIOS firmware. There are often cases when the cause of temporary computer inoperability is a trivial drop in the power supply in the centralized network. Let's not miss such an unfavorable moment as static voltage. In general, knowing how to reset BIOS settings is important and necessary!

A few words about autonomous “dependence”

This may be a kind of discovery for you, but the motherboard is equipped with a special battery, the energy of which helps keep data about the startup of the computer up to date. To elaborate on what has been said, we can add: changes made to the BIOS are recorded on a special memory microchip - CMOS.

If the above-mentioned battery fails (energy runs out), it is likely that computer system will start to get scared. By the way, a very simple action often helps to cure glitches: remove the battery from the motherboard socket and put it back in place after ten seconds.

What you need to do to reset the BIOS to factory settings

First of all, you can try to solve the above problem using the built-in tools of the firmware itself. That is, you need to go into the BIOS system and activate the recovery process manually. It is worth noting that depending on the modification of the electronic machine, its characteristics and the technologies implemented in it, the basic firmware installed on the device may differ from similar system software.

Therefore, the script for entering the BIOS on computers from various manufacturers regulated by pressing a strictly appropriate button. Basically, the duty key “Delete” or “F2” is used. In any case, when you start the computer, test information is displayed on the PC screen about which key is responsible for entering the BIOS.

Case Study

So, let's get down to the immediate point of resolving the question: “How to reset the BIOS settings”:

  • Once you are in the firmware workspace, try pressing the "F9" key. In most cases, activating this button will activate an automatic reset to default settings.

  • If " hotkey"does not work, then you should carefully inspect the BIOS interface for the presence of an inscription in the form of "Load defaults..." or something similar. Sometimes this option is hidden in one of the firmware sections.

In some cases, you can reset the BIOS settings to default by reinstalling special CMOS jumpers.

How to do this?

Before you begin this activity, turn off your computer and disconnect it from power. If you have technical documentation, you should study it carefully.

  • Unscrew the protective cover of the system unit.
  • Find the “cherished” battery on motherboard.
  • Typically, CMOS jumpers are located in close proximity to the battery.

  • Move the plastic “lock” for 1-15 seconds from position 1-2 to position 2-3.
  • Place the auxiliary part in its original place and close the housing cover.

Solutions for portable electronics

The above options can also be successfully implemented on a laptop if you need to reset the BIOS settings on the laptop. However, under such "portable circumstances" some inconsistencies may arise. In particular, access to the CMOS battery in most laptops is simply closed.

Simply put, the battery is located in the very “bows” of a compact device, and therefore, without dismantling the case parts (to get to the battery), it will be unrealistically difficult to replace the battery. Therefore, let's resort to another option, which, by the way, is also effective in relation to desktop computers.

Launch the recovery utility

Through the start menu (in the search bar) or the checkbox of the “Run” service window (press the key combination “Win ​​+ R”), enter the command: debug.

  • For AMI BIOS: O 70 FF, then “Enter” and write: O 71 FF, press “Enter” again and end with the Q symbol.
  • WITH AWARD BIOS: O 70 17, O 73 17 and Q again.

You may find this recommendation useful. However, there is another option for resetting firmware settings in laptops: close two special contacts on the system board for 10-15 seconds. However, such information is not always indicated in the technical passport of a particular computing device. For example, in some modifications of laptops, two such points are located in close proximity to the RAM of the device. In general, those who seek will always find!

Summing up

Well, congratulations, now you know how to reset the BIOS through the settings. However, be selective when choosing one or another option to restore your device to factory settings. Because the Internet is a very clever joke, and there are more than enough pranksters to advise you. Successful resets and stability for your computing device!

At the dawn of appearance computer equipment Most users were wary of such a technical innovation. In case of problems, always seek help from qualified specialists. Time has passed, and there are significantly more advanced users. There are even more people willing to experiment with their PC, changing some settings in an attempt to increase performance.

Due to incorrect settings, the system may not boot

However, as a result of unprofessional actions, mistakes may be made that lead to serious problems, as a result of which there is a need to find out how to reset the BIOS settings.

BIOS is special program, stored in the ROM chip. It is the BIOS that is responsible for starting the installed hardware. When turning on the PC, each user can hear a characteristic sound, after which the operating system starts.

Experienced owners confirm that this is how the BIOS tests devices and determines their performance. If a problem occurs, it is the BIOS that does not allow the operating system to boot, preventing more serious problems from occurring.

Reasons for resetting the BIOS

Since the BIOS is a kind of program, if desired, PC owners can make changes to its settings if they want to overclock the video card or the processor itself. In this regard, the most common reason why you have to reset the BIOS is overclocking the video card.

By overclocking a video card or processor, the user wants to increase the performance of the electronic computer. However, having set critical parameters for the above devices, the computer will once again stop booting, since the BIOS receives information that the temperature of a particular device has been exceeded.

And due to the fact that the BIOS considers this to be the highest risk, it prevents the operating system from loading further.

There is another reason that provokes incorrect operation BIOS. Like any program installed on a PC, the BIOS can also be updated. However, it may happen that the update files were initially downloaded incorrectly because they were intended for a different motherboard. By making such an illiterate update, the owner of a smart machine himself provokes poor computer performance.

Setting a password, which is subsequently safely forgotten, also directs the user to reset the BIOS.

Experts can name several more reasons why you have to think that the BIOS is not working correctly. When nothing happens when you press the power button, unusual sounds can only be made; If your computer reboots spontaneously or experiences frequent freezes, it is useful to reset the BIOS to factory settings on your PC.

How to reset BIOS

There are two ways to reset the BIOS, conventionally divided into technical and software.

Soft reset

It is quite possible to return factory default settings by going to BIOS menu. You can log in the moment you turn on your computer. When only the first inscriptions appear on the screen, the user must quickly press a certain button. This could be "F2", "F10" or "Del". In some cases, the button may be different; by reading the instructions for the motherboard, you can find out which specific button is suitable for this model of electronic computer.

By pressing the correct button, the user is taken to the BIOS menu, where you should find a parameter such as Load Optimal Defaults or something similar, since different models may have different names for this parameter.

After selecting this value, the BIOS will ask you to confirm the user's desire to reset the BIOS to factory settings. By pressing “F10”, the computer will reboot, after which the BIOS will be completely reset and the settings will return to their default state.

Resetting the factory default settings using this method is not difficult, but this method comes with both an advantage and a disadvantage. The advantage is that there is no need to disassemble the computer, violating the integrity of the warranty seal. The disadvantage is that if the reason for resetting the settings is a password that is hopelessly forgotten, then this method will be ineffective and you will have to use another method.

Technical reset

Having figured out how to reset the default BIOS settings programmatically, it would be a good idea to familiarize yourself with other options.

Initially, you should turn off the power to the smart machine, unplug the cord from the outlet, making sure that the equipment is completely de-energized.

Next, you will need to remove the system unit cover and find the place where the CMOS battery is installed. Next to it you can easily find a jumper consisting of three contacts and labeled something like CLR, Clear, Clear CMOS. The jumper installed on this jumper occupies the first and second positions, the third remains free.

Now, wanting to understand how to reset the BIOS to factory settings, you need to carefully remove the jumper and also carefully insert it into the jumper again, but in the second and third positions.

To finally reset the BIOS and return the factory default settings, the user must press the power button and hold it there for up to 15 seconds. Of course, there can be no talk of any kind of switching on, since the equipment is completely de-energized. This action is carried out in order to remove the possible remaining voltage on the capacitors, thus accurately resetting incorrect BIOS settings.

The second method is almost identical. Only in this case, it is not the jumper on the jumper that is removed, but the CMOS battery. After removing the battery, the user must also hold the power button for 15 seconds.

A technical reset of settings also does not present any difficulties, but the user must understand that warranty obligations will be lost due to damage to the warranty seal. In this regard, it is important to decide which way is most convenient to reset the settings; perhaps a better option would be to take the equipment to a service center.

Working with the BIOS requires great care, since incorrect settings can cause the computer to no longer turn on or correctly detect connected equipment. You can reset BIOS settings using three proven reset methods on your PC and laptop.

Reset in BIOS settings

If you manage to get into the interface of the basic I/O system, then there is still a chance to reset the BIOS settings through the corresponding item in the “Exit” section. This is one of the most simple options, which does not require opening the computer system unit. So, to restore the BIOS and return standard settings, follow these steps:

This method works on a laptop and is suitable for a computer. After rebooting, the BIOS settings will be set to default. All changes made by the user after purchasing the computer will be canceled.

Jumper reset

The first method works if you have access to the BIOS. To reset the BIOS settings to the factory state if you have forgotten the password, you will have to disassemble the system unit and use a mechanical jumper, changing the position of which interrupts the supply of current to the CMOS battery. The battery is responsible for storing BIOS settings, so if you temporarily turn off the power or remove it, the parameters will be reset to factory settings.


To completely discharge the remaining voltage, hold down the power button of the system unit for 10-15 seconds. The computer is de-energized, so nothing will happen. Then return the jumper to starting position and assemble the system unit. Factory settings have been installed, now all parameters in the BIOS are set to default.

Removing the CMOS Battery

Speaking of the jumper, we have already mentioned the CMOS battery, which is responsible for storing BIOS settings. Accordingly, if you remove it from the motherboard and then insert it back, you can restore the parameters that were set by default. The algorithm of actions is the same as when using a jumper.


After resetting the settings, you need to reinsert the battery and reassemble the system unit. After turning on the computer, there will no longer be any password on the BIOS, and all parameters will return to the factory state.

Reset on laptop

While it is quite easy to disassemble the system unit, you may encounter some difficulties when resetting the BIOS on a laptop. It's good if you can go into the BIOS and restore the default settings by selecting the appropriate mode in the “Exit” section. If a password is set on the BIOS, you will have to disassemble the laptop. Turn the laptop over so the back is facing you. Look to see if there is a small hole on the laptop labeled "CMOS".

If you find it, insert something sharp into the hole - for example, a paperclip. Wait for 30 seconds to reset the BIOS settings on your laptop. If there is no hole, you will have to remove back cover and look for the CMOS battery or JCMOS pins on the motherboard.

  1. Disconnect the laptop from the network, disconnect the connected devices (mouse, speakers), remove the battery.
  2. Remove the back cover (on some models it is enough to remove the protection RAM and hard drive).
  3. Remove the RAM sticks and hard drive.

Under the RAM strips there should be two contacts that are labeled “JCMOS”. They need to be closed with a screwdriver.
