Reset factory BIOS settings does not help. Instructions for returning a laptop to factory settings

It is no secret that in some cases to restore the performance of the computer system, it may be necessary to reset the BIOS. This technique allows you to eliminate many problems with the equipment that are not solved by means and tools. The following is offered several main ways to make it without any problems. Consider both software and physical methods for resetting the parameters of the primary system.

Why may need to reset BIOS?

It is often possible to meet situations where lovers to dig in the system settings set such parameters that then not that the installed equipment does not work or does not work correctly, but the operating system does not boot.

Often, you can meet and situations when a password is installed through the primary system, which does not have any relation to the operating system settings at all. Sometimes it is necessary to reset the settings to the factory even in the event that the user notices that the entire computer system works extremely unstable (constantly crashes, the reboot is performed, etc.). In some cases, this approach allows you to even restore the OS load if the problems at start were observed precisely by the wine "iron".

How to reset BIOS: Standard technique

By and large, nothing particularly difficult in the reset parameters to the factory is not. How to reset the BIOS settings? There is nothing easier.

When turned on computer device You must enter the primary system itself, using the keys to be shown on the start screen, and then go to the reset point start page. It may be called differently, but most often this is the Load Setup Defaults parameter or something like that. After its activation, the system will display a warning to confirm the reset, with which you need to agree by pressing the "Y" key (YES).

In some versions of the primary system, this item may be present in the exit menu (EXIT).

Use jumpers on the motherboard

The question of how to reset the bios can be resolved and due to physical intervention in the stuffing of a stationary computer (on laptops offered actions usually do not apply).

Here, near the battery, you can find a special jumper or so-called jumper, which is usually marked as CLRTC, Clear CMOS or has a similar name. The position in which it is set is responsible for changing the motherboard modes and reset the settings of the primary I / O system. How to reset the BIOS settings to standard? If on the board three contacts, you need to install jumper to the second position, if only two are used an additional jumper from another motherboard place to close them. Naturally, all actions must be made when the computer terminal is turned off. After that, the question of how to reset the BIOS, assumes a long pressing on the power button (for about ten seconds). A computer, understandable thing, will not turn on, but reset the settings of the primary system are guaranteed. Then you should set the jumper to the original position (as well as remove the additional jumper, if it was installed) and turn on the terminal.

Reset by removing the CMOS battery

Another technique that allows you to simply simply solve the problem of resetting the BIOS, it is to pull the CMOS battery from the motherboard's socket.

The pause between its withdrawal and re-insert is about ten to fifteen minutes. But here you need to be very careful, because on some MODELS motherboards, the battery is non-removable.

Using the DEBUG utility

Finally, the problem of how to reset the BIOS on a Windows computer on board, can be solved by using a small utility called Debug, which is the built-in tool of the operating system itself.

To start it, you need to use the "Run" menu, where the same name with the command tool is entered. After the start, a black window will appear, it does not differ from the command console. Here the parameters entered will depend solely on which version and which manufacturer is installed in the computer system.

For example, for the PHOENIX primary systems, the values \u200b\u200bof O 70 FF, O 71 FF and Q are sequentially entered, for AMI or Award systems fits the parameters about 70 17, about 73 17 and Q. But for the correctness of the reset commands, it is pre-familiar with the BIOS technical documentation, Using for this, for example, the developer's Internet resource (manufacturer). If you enter incorrect values, it can either not give any effect at all, or lead the entire system into an absolutely inoperable state.

Additional measures

In some cases, when it is only extremely necessary, you can perform the reset by installing the updated firmware that settings previous version I do not inherit.

True, it is categorically not recommended to engage like things without knowing the infancy of the flashing, and then you will have to change even the chip with the primary system, and maybe even the whole motherboard. So be careful.

RESULTS

If you make some conclusions from all that is said, reset the settings and bIOS Parameters Recommended through the options of the primary system itself. For stationary terminals, you can use zeroing by temporary dissemination of the power battery. With jumpers, too, without knowing the essence, you should be careful, and then you will be closed by those contacts, and the motherboard, which is called "will fly".

Switched something wrong to BIOS or UEFI and as a result there were problems in the computer. Something dressed in the settings and do not know how to return them by default. And maybe the computer does not start at all after changes to the BIOS. Consider how you can reset the settings before the default values.

Bios has a direct impact on the operation of the computer and its individual components. Sometimes there are times when you need to change something - switch the mode of operation of the drive, adjust the installation of the processor and the like. It may happen that they configure something wrong, and do not know how to reset to the initial values. It even happens that the computer may not boot at all - what to do in this situation?

Method 1: Resetting the settings via BIOS / UEFI

The best option is to reset the BIOS to factory values. Then all the changes you entered will be reset and everything will work as before. There are several ways to do this. If the computer turns on, then you can go to the BIOS and restore the default settings. Otherwise, if it fails to go to the BIOS, it is necessary to rule the manual way.

If the computer is turned on, information about the key will be displayed on the first screen through which you can setup. As a rule, these are the DEL orF2 keys.

These functions are responsible for restoring default values. Run one of them, and then exit BIOS by clicking on "Save and Restart".

If you have a little other BIOS window, pay attention to the options like "Load Bios Defaults", "Reset to Default Settings" or something like that. Then save the changes and restart the BIOS.

However, the same situation with recovery and in the case of UEFI, only a graphic window is characterized, which is more extensive. We go to the main UEFI window and we are looking for an option to reset to factory values.

Typically, this option is on the "EXIT" tab or displayed when you exit the UEFI - to reset the settings to the factory click on "Load UEFI Default Settings" and save them before leaving the configuration.

Method 2: Reset settings with jumpers on the motherboard

If it does not work in the BIOS on stationary computerthen you can reset using the CMOS jumper on motherboard. It is used to reset to default values.

Lay the jumper on the motherboard designed to reset the BIOS. It is usually indicated as Clear, CLR, CLRCMOS or something similar. On the computer turned off, it must be reinstalling from contacts 1-2 by 2-3 about a minute. After that, the settings will be reset.

Another way to reset the settings to the factory is to remove the battery from the nest on the motherboard. It is responsible for saving bios and system clock settings. Remove it for a few seconds and insert it back, as a result of which the settings are reset to the default values.

BIOS - a separate firmware embedded in the motherboard, which is responsible for enough wide spectrum Tasks: Specifies some computer settings, responds to control of connected devices, checks the system for performance, starts operating system etc. In the event that, for example, as a result of careless actions, the BIOS tincture was seriously changed, the discharge procedure will solve the problem.

Reset settings allows you to return the BIOS to the factory state. Such a procedure will be useful in cases where the computer does not work correctly, refuses to run the operating system and manifests many other problems with functioning.

Resetting the BIOS settings

Fortunately, the BIOS reset is provided for as many three options, each of which can be useful in one way or another.

Method 1: Perform a reset through the settings

This method is the most simple in execution, but it may not always help, because if the computer refuses to enter the BIOS, you will have to use one of the ways below.

First you need to enter the BIOS. To do this, you will need to enable your computer and at the earliest start stage of the system start pressing the key responsible for the BIOS entrance. As a rule, in the overwhelming majority of cases it is F1, F2 or DEL. However, in the role hot button A completely different key or even a whole combination.

When the input in the BIOS is completed, you can go to the search for the required partition.

In the old versions of the BIOS you will need to find a section in which the word is mentioned. "Defaults"For example, this item may be called "LOAD OPTIMIZED DEFAULTS" (execute reset to optimized settings) or "LOAD FAIL-SAFE DEFAULTS" (Performing the settings for troubleshooting the computer). Having found the necessary item, select it, and then confirm your intention to start the procedure.

In more fresh versions BIOS, which, as a rule, are found on laptops, the required reset location can be located in the output section, that is "EXIT". As a rule, this item is called "LOAD SETUP DEFAULTS".

Well, finally, in modern versions of the BIOS UEFI, control that can be carried out not only with the help of the keyboard, but also with the mouse, it should be found item "Load Defaults"which can also be located in the section "EXIT" or "Save and Exit".

By running the procedure, you will need to wait for its end. We draw your attention to the fact that at this moment there is an occurrence of power interruptions, since the sudden disconnection of the computer can lead to sad consequences.

Method 2: Perform a reset with jumpers

Another way to reset the BIOS, which implies an autopsy system Block In order to gain access to the motherboard.

Fully de-energize the computer, turning it off from the network, and then open the system unit housing. As a rule, for our problem, it is enough to remove the side cover of the housing. Pay attention to the motherboard - there should be a jumper in it, referred to "CMOS"which will allow us to reset the settings.

This jumper (differently called jumper) must be rotated to another position for seconds 5-10, and then return to the previous position. In the event that jumper only two contacts, you will need to translate it into the opposite. If the jumper has three contacts - jumper should be installed in the second position.

When the jumper is in another position, press the power button for a few seconds (five), and then release the button and return the jumper to the original position.

Collect your computer and run it. From this point on, reset the BIOS settings can be considered completed.

Method 3: Reset Using the Battery

On the motherboard there is a special battery that stores bIOS settings. Removal I. re-installation This battery will allow the reset of all parameters to the factory.

To accomplish this procedure, we, again, it will be necessary to access the insides of the system unit. To do this, de-energize the computer, remove the system unit housing and find the BIOS battery on the motherboard (it usually is located next to the CMOS jumper).

Near the battery, click on the latch, after which the battery must run away. After 10 seconds, return the battery to the previous position.

We draw your attention to the fact that some motherboards are equipped with fixed batteries. If the battery does not have a latch, you should not "pass out" the battery - just this method It is not suitable for you.

Collect your computer and run it. Reset BIOS settings completed.

All three ways are effective. What to choose is to solve you, based on the status of a computer and your features.

At the dawn appearance computer equipment Most users with caution treated such a technical innovation. In the event of problems, they always appealed for help to qualified specialists. Time passed, advanced users became much more. Even more wishes to experiment with their PC, changing some settings, trying to increase productivity.

because of incorrect settings The system may not be loaded

However, as a result of non-professional actions, errors may be allowed, resulting in serious problems, as a result of which there is a need to learn how to reset the BIOS settings.

BIOS is special programstored in the ROM chip. It is the BIOS that is responsible for launching installed equipment. When the PC is turned on, each user can hear the characteristic sound, after which the operating system is launched.

Experienced owners confirm that thus BIOS tests the devices, determines their performance. In the event of a problem, it is the BIOS that does not allow the operating system to boot, preventing the occurrence of more serious problems.

Causes of BIOS reset

Since BIOS is a kind of program, if desired, the PC owner can make changes in its settings, wanting to disperse the video card or directly the processor itself. In this regard, the most common cause in which you have to implement bIOS resetis exactly overclocking the video card.

Accelerating the video card or processor, the user wishes to increase the performance of the electronic computing machine. However, by specifying critical parameters for the above devices, the computer will once again stop loading, since the BIOS receives information about the exceedment of the temperature mode of the specific devission.

And due to the fact that BIOS considers it as the highest risk, it prevents further loading of the operating system.

There is another reason provoking the incorrect operation of the BIOS. Like any program installed on the PC, the BIOS may also be updated. However, it happens that the update files were initially loaded incorrectly because they were intended for another motherboard. By producing such an illiterate update, the owner of the smart car itself provokes poor work Computer.

Installation of a password, which is subsequently forgotten, also focuses the user to reset the BIOS.

Specialists can call a few more reasons, as a result of which they have to think about the fact that BIOS works incorrectly. When, when you press the switch button, nothing happens, not quite familiar sounds can be published; If the computer spontaneously reboots or exposed to frequent freezes, it is useful to reset the BIOS to the factory settings on the PC.

How to Reset BIOS.

You can reset BIOS in two ways conditionally divided into technical and software.

Software reset settings

Return the factory default settings is quite possible, going into menu Bios.. You can implement such an input at the time on the computer. When only first inscriptions appears on the screen, the user must quickly press a specific button. It may be "F2", "F10" or "DEL". In some cases, the button can be different by reading the instructions for the motherboard, you can find out which specifically the button is suitable for this model of the electronic computing machine.

Pressing the correct button, the user falls in the BIOS menu, you should find such a parameter as Load Optimal Defaults or something similar because different models A different name of the specified parameter can occur.

After selecting this value, BIOS will ask to confirm the user's desire to reset the BIOS to the factory settings. By pressing the "F10", the computer will restart, after which the final BIOS reset will occur, the settings will return to the default state.

Return the factory default settings in the specified way is easy, but this method is accompanied by the advantage and disadvantage. The advantage is that there is no need to disassemble a computer, violating the integrity of the warranty seal. And the disadvantage is that if as a reason that provokes a reset, the password, which is hopelessly forgotten, will be ineffective, this method will have to use another method.

Technical resetting settings

Having understood how to reset the BIOS settings by default by the programmatically, it will not be superfluous with other options.

Initially, you should turn off the power of the smart machine, pull the cord from the outlet, making sure that the technique is complete.

Next, you will need to remove the system unit cover and find the location where the CMOS battery is installed. Next to it is easy to detect a jumper consisting of three contacts and signed by something like Clr, Clear, Clear CMOS. The jumper installed on this jumper occupies the first and second position, the third remains free.

Now, wanting to understand how to reset the BIOS to the factory settings, you must carefully remove the jumper and also gently insert it into the jumper, but already on the second and third position.
