Your Dell computer’s Basic Input/Output System (BIOS) allows you to make changes to your hardware. If you wish to set boot or hardware passwords, enable or disable hardware components or adjust laptop LCD brightness, you will need to access the BIOS. It also offers system monitoring, such as processor speed, memory, temperatures and fan speeds. Adjusting the boot sequence, which can force the computer to boot from a CD or USB device, can also be done in the BIOS. Writer Bio
