Certain problems on a Windows computer like keyboard keys not working, random restarts and others might require you to update BIOS.
Newer computers have replacement BIOS chips known as UEFI (Unified Extensible Firmware Interface) that support larger disk size and faster boot time compared to older BIOS chips.
The main function of BIOS/UEFI on a computer is to initialize CPU, GPU, Disc Drives, other hardware components and load the default operating system on the computer.
Hence, just like any other software program, BIOS needs to be updated in order to maintain its compatibility with hardware and software running on a computer.

Make sure that your computer is connected to a direct power source (AC adapter), as BIOS can get corrupted if the computer turns OFF during BIOS update.
It is recommended that you Backup your data before updating BIOS. Errors during BIOS update can lead to a loss of data.
