Resetting your computer's BIOS settings - how and why. Bios Settings - Detailed instructions in pictures

BIOS (Basic input/output system) – basic settings computer input/output. Processor operation, RAM, boot priority, time and date are configured through the BIOS. Sometimes, if errors occur related to booting the computer, resetting or restoring the settings to factory settings can help. In this article we will try to describe possible options How to reset bios to factory settings.

Reset Bios to factory settings

There are several options to reset Bios settings to factory settings:

• Through BIOS settings(program);
• Via jumper or reset CMOS(hardware).

Let's look at these options separately.

Option 1

Through BIOS settings. This method allows you to quickly and easily reset settings via uefi bios to factory ones. It eliminates direct access to the computer hardware and is perfect if the operating system does not load. Difficulties may arise for users who may not be well versed in English names or words.

Procedure:

• Restart your computer;
• When rebooting, press the key that brings up the BIOS. The required key may be indicated on loading screen, accompanied by the designation Setup. Depending on the manufacturer of the laptop or motherboard, the keys may be Esc, Del, F2, F8, F12
• Go to the Settings or Exit tab. In this tab you need to find the following items:
  - Load Default Settings;
  - Load Default;
  - Load Setup Default;
  - Or other similar combinations.
• Exit settings, saving your current changes.

Option 2

Using a jumper. This option It will be ideal if you need to reset the bios settings to default settings, but you cannot access it due to an error or failure. This jumper is present on each motherboard– personal computer or laptop.

Procedure:

• Turn off your computer;

• On the motherboard, find a jumper with the following designations
  - CLEAR CMOS;
  - CLEAR;
  - CLR CMOS;
  - CLR PWD.

If the jumper has 2 contacts, open it (remove the jumper) for a few minutes and connect it back. If 3 pins, connect a jumper alternative way(for example, from position 1-2 to position 2-3).

• On a laptop: remove the RAM sticks. Under them, find 2 contacts labeled CLEAR, CLEAR CMOS and others. These pins must be closed to reset the CMOS.

Warning! Not all laptops have these contacts; the following option is suitable for them.

Option 3

By removing the CMOS battery. This method is the most difficult/inconvenient when using a laptop, but sometimes it is the only one, since the manufacturer did not offer other options. This method will help solve the question of how to reset the bios settings on a laptop (HP, Asus, Lenovo, Acer and others) to the preset value.

Procedure:

• Turn off your computer;
• Turn off the power to the device (remove the laptop battery or disconnect network cable from the system unit's power supply) and remove the computer cover.

Necessarily! Make sure there is no static current or use special antistatic materials.

• For computer. There is a small round CR2032 battery on the motherboard. This battery supports power dynamic memory(CMOS) so that every time you shut down or restart your computer you don't have to reconfigure all the hardware and boot settings. It must be removed for 2-3 minutes and reconnected.
• For laptop. Remove the laptop cover until you reach the small battery. It differs slightly from a “computer battery”, in that there are 2 wires coming from it, these contacts are connected to the motherboard to maintain CMOS functionality. Disconnect the contacts for 2-3 minutes and reconnect.
• Assemble your system unit or laptop, connect it to power and turn it on.

Resetting parameters to factory settings is not always difficult and unclear; it is enough to have the appropriate instructions at hand.

Have a great day!

Greetings!
BOIS stores information and manages basic equipment what is installed on your computer. The BIOS is also responsible for the correctness of the time displayed in the operating system.

Why reset BIOS settings

Resetting the BIOS settings to their original settings may be necessary in the following situations:

1) Have you installed any additional equipment into your PC, but refuses to be detected by the operating system, or problems arise with its operation: the equipment disappears from the system from time to time, the system freezes, etc.

2) In an attempt to overclock your computer, you have set parameters in the BIOS that are not actually supported by the hardware installed in your PC. As a result, the computer stopped turning on altogether.

3) You have updated the BIOS, and in this situation it is recommended to reset the settings.

4) There is a need to reset the password that is requested when you turn on the computer (before actually loading the installed operating system).

This material will describe in detail and demonstrate with specific examples how to reset the BIOS settings to default (default) on a personal computer and laptop. We will consider resetting the settings both from the BIOS itself and by directly switching the contact\battery on the computer motherboard that powers BIOS chip and does not allow you to “forget” saved settings.

Resetting the BIOS through the corresponding menu item

The simplest and most logical way to reset BIOS settings is to use the menu item that is available in the settings of the BIOS itself.

It should be noted that this item is available in almost all versions and variants of BIOS, however its name and location may vary.

To orient you, I will show you specific example location of this item in a standard BOIS.

To enter the BIOS settings you need straightaway after turning on (even before the operating system itself boots), press the key several times Del on the keyboard of a personal (stationary) computer, or another key if it is a laptop. The key most often used to enter the BIOS on laptops is F2.

In the once popular and widely used BIOS version This item was located in the main menu:

Load Fail-Safe Defaults- reset BIOS parameters and settings to default. In this mode, all computer components will undergo a full test. It is recommended to use it before installing the operating system and if you suspect that some component is working intermittently, for example, a RAM stick.

Load Optimized Defaults- if you select this item, the BIOS settings and parameters will also be reset, but with a focus on optimization. IN this mode Some components will undergo a “reduced” test, which will make the computer boot faster.

If we talk about laptops, then everything is somewhat more complicated. They have an interface BIOS menu can be heavily redesigned and stylized to match the company's brand.

For example, in an HP laptop the BIOS looks like this. Here, resetting the settings is carried out by selecting the item Restore Defaults.

The name of the item that resets BIOS settings may be different, namely: Load Setup Defaults, Load Optimized Defaults, Reset to Default, Factory Default, Setup Defaults and consonant. The location may also differ; most often this item is located in the tab Exit.

Based on the above, you will need to find this item in your BIOS version (including UEFI) and click on it. Navigation in the BIOS is carried out using keys arrows, and select with the key Enter.

After resetting the settings, the computer will either restart or you will need to exit the BIOS with the settings that were reset to the default option saved.

If you do not have access to the BIOS due to set password, or the computer refuses to turn on at all after “experiments” with the BIOS settings (optionally, in an attempt to overclock the computer), then the following method of resetting the settings will suit you.

Resetting the BIOS via a jumper on the motherboard

Most computer motherboards have jumpers that physically consist of pins and, if necessary, are shorted using attachments (jumpers). By closing/opening certain jumpers, the configuration of certain PC parameters is carried out.

By closing the jumper that relates to the BIOS, the settings will be reset to the default option.

For reset BIOS By using a jumper you need to do the following:

Disconnect the computer from the electrical outlet by unplugging the cord from the outlet. After which you need to arm yourself with a screwdriver and unscrew the screws that hold the side cover of the computer.

Having gained access inside, you will need to find a jumper on the motherboard located there, which is responsible for resetting the BIOS settings and parameters. In most cases, this jumper is located near the battery, which powers the BIOS and prevents you from forgetting the settings.

As a guide, the jumper is often labeled accordingly: BIOS RESET, CMOS RESET, CLEAR CMOS, and the text can be abbreviated, for example, CLR_CMOS.

The jumper itself can consist of two or three pins. If there are three pins, then move the jumper to the next pair of pins, and if there are two, then you should borrow a jumper from another place on the motherboard. Just before borrowing a jumper, remember, or better yet, take a photo of its original position.

After this, you need to hold the power button for about 10 seconds. The computer, of course, will not turn on because... completely de-energized, just this procedure necessary to reset BIOS settings.

Having done this, return the jumper to its original position, and then put and screw back the computer cover, connect the power.

Done, the BIOS has been reset. Now you can configure the BIOS settings again, or use those that were set by default.

Method for resetting BIOS with removing the battery

The BIOS reset jumper is in most cases located next to the battery. This is due to the fact that the chip in which the BIOS settings are stored is not non-volatile. This battery It just feeds the BIOS, allowing you to save user-specified settings, as well as maintain the operation of the built-in clock during periods when the computer is de-energized.

After pulling the latch, carefully remove the battery for a few minutes, and then return it to its place - the BIOS settings and parameters will be reset.

It should be noted that in rare cases the battery is not removable. Take this fact into account if you see that the battery is very firmly seated in the slot.

Brief summary

Now you know in what cases you should resort to resetting the BIOS, and how this can be done. The first method is universal, and the second and third are more suitable for stationary personal computers. Laptops also have a battery that powers the BIOS, but getting to it is often much more difficult.

If after reading the material you still have questions, do not hesitate to put them in the comments.

We switched something wrong in the BIOS or UEFI and as a result, problems arose in the operation of the computer. You messed up something in the settings and don’t know how to return them to default. Or maybe the computer does not start at all after changes to the BIOS. Let's look at how you can reset the settings to default values.

BIOS have 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 drive operating mode, adjust processor settings, and the like. It may happen that we configure something incorrectly and don’t know how to reset it to its original values. It even happens that the computer may not boot at all - what to do in this situation?

Method 1: Reset via BIOS/UEFI

The best option is to reset the BIOS to factory settings. Then all the changes you made 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 into the BIOS and restore the default settings. Otherwise, if you cannot enter the BIOS, you will have to edit it manually.

If the computer turns on, the first screen will display information about the key through which you can Setup. As a rule, these are the Del or F2 keys.

These functions are responsible for restoring default values. Launch one of them, and then exit the BIOS by clicking on “Save and restart”.

If you have a slightly different BIOS window, pay attention to options like “Load BIOS defaults”, “Reset to default settings” or something similar. Then save the changes and restart the BIOS.

However, the situation with recovery is the same in the case of UEFI, only the graphic window is different, which is more extensive. We go to the main UEFI window and look for the option to reset to factory values.

Typically this option is located on the “Exit” tab or is displayed when exiting UEFI - to reset the settings to factory settings, click on “Load UEFI default settings” and save them before leaving the configuration.

Method 2: Reset using a jumper on the motherboard

If you cannot enter the BIOS on desktop computer, then can be reset using the CMOS jumper on the motherboard. This is used to reset to default values.

Find the jumper on the motherboard designed to reset the BIOS. It's usually labeled Clear, CLR, CLRCMOS, or something similar. With the computer turned off, it needs to be reinstalled from contacts 1-2 to 2-3 for about a minute. After this, the settings will be reset.

Another way to reset the settings to factory settings is to remove the battery from the socket on the motherboard. It is responsible for saving BIOS settings and system clock. Remove it for a few seconds and insert it back, which will reset the settings to default values.

Working with the BIOS requires great care, since incorrect settings lead to the computer no longer turning on or correctly detecting 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 basic system I/O, 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 flow of current to the CMOS battery. The battery is responsible for storing BIOS settings, so if you temporarily de-energize it 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 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 of the 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.

This article will talk about ways in which you can reset the BIOS settings on your computer or laptop if any problems arise in its operation.

Useful articles on the topic

Sometimes, for a variety of reasons, it is necessary to reset the BIOS settings of a computer (motherboard). These settings store most of the parameters that are responsible for the operation of the computer and all its devices. Below are several ways to reset these settings to default values :

Resetting BIOS settings via the BIOS menu

This method is suitable if you can access the BIOS when you turn on the computer. To do this, when you turn on the computer, press a special button, which is responsible for entering the BIOS settings. Most often, this button is the Del (Delete) button.

Further actions depend on the manufacturer of the motherboard and the BIOS in it. It should not be difficult to distinguish which BIOS is in the motherboard visually; just look at the explanatory pictures for the instructions for each type of BIOS.

Select "Load UEFI Defaults".

To the question "Load UEFI Defaults?" We answer “Yes”.

Now select the “Save Changes and Exit” item.

To the next question in the form “Save configuration changes and exit setup?” We answer “Yes”.

After this, the BIOS settings will be reset and the computer will restart.

Resetting BIOS settings in ASUS UEFI BIOS

In maternal ASUS boards there are two UEFI interface- one was used on old motherboards released before about 2014, the second is used on all currently produced motherboards. Therefore, if you do not visually recognize the interface of your BIOs/UEFI, do not rush to close the page with these instructions, but simply scroll further.

First option

In the lower right corner, look for the “Default (F5)” button and click on it.

A window will appear asking you to confirm the action being performed. Select "OK".

Now the main menu will open in front of us again. On the right top corner Find the "Exit/Advanced Mode" button and click on it.

Select "Save Changes & Reset".

The computer will reboot and the BIOS settings will be reset.

Second option

Press the F5 key, or the " Default (F5)" at the bottom of the screen.

In the window that appears, select " OK", or press the Enter key.

Then select " Save & Exit(F10)" (or press the F10 key).

And press again " OK", or the Enter key.

Reset BIOS Settings in MSI UEFI BIOS

In the BIOS main menu, select "Mainboard settings" ("Settings").

Select the item "Save & Exit".

In the menu that opens, select "Restore Defaults".

A window will appear asking you to confirm the action - “Load Optimized Defaults?” We answer "YES".

Now you need to exit, saving the reset BIOS settings. To do this, go to the “Save Changes and Reboot” item.

When asked if we really want to reboot - Save configuration and reset - we answer "YES.

The computer will then restart and its BIOS settings will be reset to default settings.

Resetting BIOS settings by removing the battery

First you need to turn off and unplug your computer.

To do this, you need to find the power supply on the back of the system unit and turn it off with a special button. It is also a good idea to pull out the power cord from it; this is necessary if there is no power switch.

Inside you need to find a CR2032 round battery, most often it is located at the bottom of the motherboard. In order to remove the battery, you need to press the special holder.

After the battery is removed, you need to hold down the power button for 10-15 seconds. Since the system unit is de-energized, it will not turn on, but it will completely discharge any existing accumulated electricity in the computer. At the same moment, the BIOS settings will be reset.

Now you can close the system unit by returning the cover to its place, plug in the power cord and turn on the power supply, after which you can turn on the computer.

Resetting BIOS settings via jumper

We de-energize the system unit by turning off the power supply with a special switch located near the entrance to the power cord.

Next, remove the cover of the system unit and get inside the computer. Now we are looking for a special jumper on the motherboard. It looks like a blue (in most cases) jumper that is connected to two pins; there should be three pins in total. Typically, such a jumper is labeled as “Clear CMOS”, “CLR”, “CLEAR”, “PSSWRD”.

To reset BIOS given The jumper needs to be moved one pin to the side. Those. Initially, the jumper covers pins 1 and 2 - we need to connect it to pins 2 and 3.

After this, you need to hold down the computer's power button for 10-15 seconds to finally discharge the remaining electricity into system unit. After this, the BIOS settings will be reset.
