A computer's BIOS system runs independently from the computer's operating system. Inside of the computer, the BIOS settings are saved using a lithium ion battery. This is referred to as a CMOS battery. Even when the laptop loses its power, the BIOS settings will be saved as long as the CMOS battery has enough charge left in it. If the BIOS settings are frequently being reset, the CMOS battery needs to be replaced. The Compaq Nc6320 laptop computer's CMOS battery is easily accessible by way of the keyboard.
