Reset bios on laptop. How to reset bios on asus laptop. Reset BIOS settings on a laptop by disconnecting the battery

Many problems that arise when working at a computer are quite simply solved by resetting (zeroing) the BIOS to factory settings. Most often, users themselves create these problems when overclocking the processor, making critical changes to the BIOS, or setting a password on the BIOS and forgetting it. Zeroing the BIOS is not a complicated process, there are several ways. Consider the most common and simple.

One way is to perform a mechanical reset. Be sure to turn off the laptop, turn it over and look for a small hole on its back near the inscription “CMOS”. To reset the BIOS settings, insert a small sharp object, such as a needle or the end of a paperclip, into this hole. Hold it in this position for no more than 10 seconds. The next way is to remove the battery responsible for powering the CMOS memory even when the laptop is turned off. If the described technological hole is not on the laptop, then you will have to remove the bottom cover of the laptop. Remove all screws with a Phillips screwdriver and carefully separate the cover. In order not to damage the wires, disconnect a few cables from the sockets.



Find a battery. It is not difficult to do this, it is located on the motherboard, it looks like a flat washer. Remove the battery from the slot using a thin screwdriver. Please note that capacitors hold a charge for quite a long time and the settings will not be reset in a few seconds. It is usually recommended to hold a laptop without a battery for several hours, or rather, a day. If the battery is soldered, you will have to unsolder it and replace it. Attach the battery, assemble the laptop, turn it on.



You can do without pulling out the battery if you find a special jumper on the motherboard. Find a switch (jumper) next to the battery, it may have two or three pins. If there are two contacts, then simply close them, if there are three contacts, then move from position 1-2 to position 2-3 for a few seconds. To find the right pins, you need to read the user manual for the motherboard. In expensive boards, instead of a jumper, there may be a reset button labeled CMOS.



If a mechanical way to reset the BIOS settings is undesirable, then you can use the software method. Turn on your Asus laptop, press "Esc" or "F2" key. A menu will appear on the screen, select “Start BIOS”, then press the “Enter” key.



After loading the next menu “Motherboard Settings”, go to the “Main” tab, the transition can happen automatically. Use the cursor arrows to highlight the menu item “Set BIOS Default” or “Use Default Settings”, press “Enter”. Respond to the prompt by pressing the “Y” key, confirm the reset of the parameters.



Go to the next menu item - "Save & Exit", press the "Enter" key, confirm the action - the "Y" key. Now the Asus laptop will reboot with the default (standard) BIOS settings.



It is not necessary to reset the BIOS without unnecessary necessity. If the system works without failures, loads well, it is better not to touch the battery. If the settings are automatically reset to factory settings every time you boot up the computer, then the battery most likely needs to be replaced. Keep in mind that the mechanical method will require you to disassemble the laptop, and you may void the warranty on it. Therefore, to solve problems, it is better to contact the service center.

Hello admin, tell me and if possible show me how to reset the BIOS on a laptop? I must say that I pretty much experimented with it, even Windows doesn’t load now, I changed various settings in the Advanced and Boot tabs, which I don’t remember now, I just didn’t change anything in the Main tab.

I went to one computer forum to ask what to do, they gave such advice, reset the BIOS settings to the factory settings, it seems like you need to enter the BIOS and press the F3 key, then OK, but in my case it does nothing, I pressed both F2 and F3 , and F5, but all to no avail. I ask you to give me advice, the user level is a beginner. Toshiba laptop. Regards, Yuri.

How to reset BIOS on a laptop

Hello friends! If you changed the BIOS settings, so much so that the laptop stopped booting, here's what you need to do. By the way, this also applies to the BIOS of a simple stationary computer, enter the BIOS and reset the settings to the factory settings, sometimes they also say - reset the BIOS to default, this is guaranteed to cancel all your incorrect changes made in the laptop BIOS.

This is very easy to do and takes literally seconds. On almost all existing new laptops, this operation looks the same, since the manufacturer of the BIOS utility itself with EFI elements is the same for everyone - InsydeH2O. The keys are mainly responsible for resetting to factory settings F9. If you have a not quite new laptop, then the F3 key.

I offer you reset BIOS on laptops various manufacturers.

How to reset BIOS on a Toshiba, Acer, Samsung, HP laptop
So, we turn on the computer and in the very initial phase of loading we often press the F2 key (most often). We enter the BIOS and immediately pay attention to the instructions at the bottom of the window or in the lower right corner. The inscription F9 Setup Defaults tells us that to reset the BIOS settings, you need to press the F9 key.

We press F9, a window appears, in it we must confirm our intentions Load setup defaults (Reset default settings), select Yes and press Enter on the keyboard. Everything, the settings are reset.

Then press F10 to save the settings and reboot.

When you turn on a laptop, rarely anyone asks where the laptop knows how and what to download. Responsible for the correct loading of the device is the BIOS program - the basic input / output system. First of all, BIOS algorithms are executed, and only then, the computer comes under the control of the operating system installed on it.

Sometimes failures occur at the boot stage, which means that some user settings interfere with the full launch of the laptop. Resetting the BIOS on a laptop is just a return to the factory, otherwise, safe settings.

Resetting is carried out in two modes, automatic and manual. First, let's look at how to reset the BIOS on a laptop automatically if a password is not set on the BIOS.

On most laptop models, entering the BIOS is done by pressing the F2 or DELETE key. Surely this can be found when the system boots. After entering the BIOS, you should find the Exit tab. Select the line "Load Setup Defaults", which means loading the default settings.

After that, a window will appear on the display where you need to confirm your intentions by selecting OK. After resetting the settings to the factory settings, you should exit the BIOS by selecting the Save and Exit line, or by pressing the F10 key.

There are situations that the BIOS settings are protected by a password, which for some reason cannot be entered. Therefore, further we will consider how to reset BIOS on an Asus laptop. However, modern laptops do not differ much by manufacturer, and this method is quite universal.

First of all, you need to disconnect the laptop from the mains and remove all peripheral devices (mouse, modem, speakers, etc.). Next, you need to perform the following steps:

  1. Take out the battery
  2. Remove the cover under which the hard drive and RAM board are located.
  3. Carefully remove them from the case and find the contacts closed by a jumper (jumper) on the motherboard. As a rule, they are marked Clear / CLR / CMOS / C_CMOS, depending on the equipment model.
  4. Move the jumper that closes the first and second contacts so that the second third is closed
  5. After 15-20 seconds of waiting, return the jumper to its original position
Note: on older laptop models, there is a system with two contacts. In this case, you can resort to the help of improvised means and close the contacts, for example, with a screwdriver. In modern models, there is a special button on the motherboard, which allows you to restore the settings with one click..

After these manipulations, the system will be restored. As a last resort, you can reset the bios settings by removing the battery from the motherboard connector, but this method is longer and less reliable, because resetting the parameters can take up to several hours. These actions will not only reset the settings, but reset the BIOS password on the laptop.

Working with the BIOS requires great care, since incorrect settings cause the computer to stop turning on or correctly detect connected equipment. You can reset BIOS settings using three proven reset methods on a PC and laptop.

Reset in BIOS settings

If you manage to get into the interface of the basic input / output system, then there is a chance to reset the BIOS settings through the corresponding item in the "Exit" section. This is one of the simplest options that does not require opening the computer's system unit. So, to restore the BIOS and return the default settings, follow these steps:

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

Reset via jumper

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


To finally discharge the remaining voltage, hold down the power button of the system unit for 10-15 seconds. The computer is dead, so nothing will happen. Then return the jumper to its original position and assemble the system unit. The factory settings are set, 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 the 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 must insert the battery into place and assemble 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

If the system unit is easy to disassemble, then when resetting the BIOS on a laptop, you may encounter some difficulties. Well, if you can go into the BIOS and restore the default settings by selecting the appropriate mode in the "Exit" section. If a BIOS password is set, then you will have to disassemble the laptop. Flip the laptop over with the back facing you. Look for a small hole labeled "CMOS" on the laptop.

If found, insert something sharp into the hole, such as a paper clip. Hold for 30 seconds to reset the BIOS settings on the laptop. If there is no hole, you will have to remove the back cover and look on the motherboard for a CMOS battery or JCMOS pins.

  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 signed as "JCMOS". They need to be closed with a screwdriver.

In the event that the device starts to malfunction, you may need to find out how to reset the BIOS to factory settings. The BIOS is a set of control microprograms that loads the operating system (Windows, Linux, etc.) on computers and laptops.

This is the basic input and output system found on the motherboard. The key functions of this element are setting the system time, boot priority, power settings, etc.

Why You Might Need a BIOS Reset

Factory BIOS settings are the most secure and optimal. Therefore, returning to them helps to solve many problems on a computer or laptop. Among them:

  • Resetting the password in case of its loss;
  • For overclocking (critical parameters were set for the bus frequency or memory timings);
  • When an incorrect setting was made indicating an erroneous parameter;
  • The computer stopped booting.

In these and many other situations, understanding how to reset the BIOS can help save a significant amount of time and effort. If the computer is still under warranty, then it is better to contact a store or service center, as you can lose the right to free service due to interference.

Reset BIOS in different ways

Before you figure out how to reset the BIOS on a computer, you should understand how to log in to the system. You can get into the BIOS in this way: at startup or reboot, start pressing the F2 or Delete key (this will depend on which motherboard is installed in the device, you can try pressing different options until you get the desired result).

Management is carried out in this mode using five buttons. The right and left arrows will allow you to navigate through different sections, choosing the configuration options of interest. The Enter button helps to apply the selected setting or enter a section. To exit, use ESC. Now you can figure out how to reset the BIOS to factory settings - this is done by pressing the F9 key. To then save the changes made, you should use F10 (it will also help you exit the menu later).

There are several completely different ways to reset the BIOS to factory settings. It could be:

  • Creation of programs for writing various values ​​to ports;
  • Closing microcircuits at contacts;
  • All kinds of operations with jumpers and so on.

But the simplest and most understandable for many is the method with the usual pulling out of the battery, which is responsible for providing constant power to the BIOS memory even if the computer is turned off. What we need to do:

  • Disconnect the power cord from the power supply so that the system unit is de-energized;
  • Find a flat-shaped battery on the motherboard (usually located closer to the edge of the motherboard, large enough);
  • Use a thin screwdriver to pull out the battery (if there are holders, gently bend them).

After removing the battery, at least 5 minutes must elapse. (In some cases, you will have to wait about a day). After it is installed back, and the holders also carefully return to their place. Next, power on the computer and boot up. Now all settings should be reset to default.

Difference between process on PC and laptop

Unless you really need to figure out how to reset BIOS on a laptop or computer, it’s not worth it, especially if the system boots normally. Resetting the settings on a computer is easier than on a laptop. In the case of laptops, it is much more advisable to contact a service center (preferably one authorized by the manufacturer). Most often, laptop users want to reset the BIOS due to a forgotten password, since there are usually no problems with overclocking (there are simply no corresponding options).

Another difference is that on laptops from different manufacturers, the reset process can be carried out using various buttons (most often F2 or Esc) and a sequence of actions. So, resetting an Asus laptop to factory settings is done by pressing the F2 key (entering the settings) at boot, switching to the “Boot” option, selecting the Boot Booster function (you need to set the shutdown to the item). Next, you need to save the settings as standard and reboot. In all other cases, the process may differ for different manufacturers, with computers in this regard it is somewhat easier.

When looking for a solution on how to reset BIOS settings to default, one important point should be considered. Boards with good quality, even if the battery is removed, can hold the parameters for half an hour or more. In this case, a special jumper (jumper) is provided near the battery.

It is marked CLR or prefix CMOS. By closing its contacts, the settings are reset instantly.

Now you will learn how to reset the BIOS to factory settings.
