How to reset the BIOS and reanimate the computer

If the computer shuts down for no apparent reason, does not turn on or you forget the BIOS password, try resetting the settings.

A reset can also be useful when Windows does not boot, or the computer is unstable. If these problems occur after changing the BIOS parameters or a failure in the firmware, these instructions can help you.

Recall, the BIOS is a software environment that manages the primary functions of the computer and is the interface between the hardware and the operating system. After the reset, the files on the drives and the Windows settings will remain intact. But, most likely, you will have to go into the BIOS, find the section with the time and date parameters and re-configure them.

All these methods of reset are suitable for both desktop computers and laptops.

1. How to reset the BIOS via the programming interface

The easiest way to reset the BIOS is to open its interface and use the reset command. But this option is suitable only if the computer turns on and you remember the BIOS password or did not install it.

To get into the interface, in the first seconds of turning on the computer, press F1, F2, F8, Delete or another key until you see a menu with settings. Typically, the desired button is displayed at the bottom of the screen when the device is started.

Once in the BIOS menu, look for an item with the name Reset to Default, Factory Default, Setup Defaults or Load Optimized Defaults. Usually, this option is in the Exit section. Use it and confirm the action – the computer will reboot, and the settings will be reset.

If for some reason you can not get into the BIOS interface or find the desired item, try the following methods. But for this, you will need to remove the cover of the case to gain access to the motherboard.

Remember, opening the case can lead to a loss of warranty.

2. How to reset the BIOS using a jumper or a button on the board

Turn off the computer and unplug it from the wall outlet and other devices. If you have a laptop, remove the battery. Then remove the housing cover and inspect the motherboard.

On some new models of cards, there is a particular button for resetting BIOS settings. Usually directly on it or nearby you can see inscriptions like CLEAR, CLR, PSSWRD or CLR_CMOS. If you find such a button on your motherboard, just click on it. The BIOS settings will be reset, and you will only need to compile and turn on the computer.

If there is no such button, next to the battery, there should be a so-called jumper – a particular jumper, with which you can perform a reset. It takes two contacts out of three. Remove it and put it on the other two connections.

While the jumper is in a new position, press the power button on the computer and hold it for 10-15 seconds. The computer will not turn on, as it is de-energized, but the BIOS will reset. After that, you can return the jumper to the old place, and then collect and turn on the computer.

If this method does not work or you can not find a jumper, try the following.

3. How to reset the BIOS using a removable battery

BIOS settings are saved even when the computer is not connected to power supplies. This is due to the battery on the motherboard, which always feeds the microcircuit. But if you extract it for a few minutes, the BIOS will reset.

Turn off the computer and unplug it from the wall outlet and other devices. If you have a laptop, remove the battery.

Remove the housing cover and locate the battery on the motherboard. Then gently remove the battery for 10 minutes and plug it back in. Do not overdo it: in some devices, it can be immovable. In such cases, it remains to rely only on previous methods or to return the device to a service center.

On many laptops, the battery is connected to the motherboard using individual wire. If you notice this, unplug the cable from the board before removing the battery.

When reinstalling it, close the case, if necessary, replace the battery and turn on the computer.
