The computer has a special solid state IC. This is called the BIOS (Binary Input Output System). The Integrated Circuit (IC) has a program on it that tells the computer how to start and also runs a few tests when you turn the computer on. In addition, the computer has a BIOS clock. The battery allows the computer to retain BIOS settings and the time when the computer is unplugged.

Desktop computers use small lithium watch batteries to keep settings and the clock going when the computer is turned off. Notebook computers, MP3 players and cell phones use lithium-ion batteries to power themselves. Lithium-ion batteries are rechargeable, lithium batteries are not.

Primarily the time of day clock but also user adjustable things like number and type of drives, allocation of internal I/O ports and interrupts (IRQs) special video seetings, and a lot more that vary from one pc to another

On a laptop it is used to power the laptop while not plugged it, making it portable which is the major reason laptops exist.
