How to reset BIOS: 3 methods

A computer BIOS is an integral part of a computer that allows you to manage various components of a modern computer, providing a correct and consistent way to start devices. The job of the BIOS is as follows: as soon as you press the Power button, the BIOS starts testing and activating whatever it needs to run. If the test is successful, it sends a signal to your operating system to activate. Further, the processor monitors the operation of the computer.

Today, you can find BIOS and UEFI, but they are often used interchangeably. The purpose of BIOS and UEFI is the same, but they differ in how they achieve the desired effect.

To reset the BIOS or UEFI settings of your computer, you can use one of three methods:

• Internal reset from the BIOS menu of your device;

• Need to remove the jumper on the motherboard;

• Reset by removing / replacing the CMOS battery.

Reset from BIOS or UEFI

This method is the most secure; therefore, it is most often preferred by users.

So, start restarting your computer and hold down the Shift key.

You will be taken to a blue screen with advanced troubleshooting options.

In the options, select Troubleshoot and click Advanced options. Next, select "UEFI Firmware Settings". Now, click on the "Restart" option. After rebooting, you will automatically be taken to the setup menu, where you should find the default reset button. Click on the "Load defaults" option and select yes. Now, the default settings should be restored. Exit this window and start the system as usual.

Clear motherboard jumper

This method is most often used on desktop PCs and requires the utmost care and attention. Therefore, in the beginning, you need to study the manual (it is better to watch the video manual) of the user and make sure that you can correctly identify the motherboard jumper. Then you need to access the motherboard (all safety procedures are described in the paragraph “Replace CMOS battery”, do not neglect them).

Once you have access to the motherboard, locate the jumper as written in your manual (often next to the CMOS battery or along the small plastic pin with the appropriate tongue) and remove it.
