Clock Battery ( CMOS)

The clock battery (otherwise known as the CMOS battery) is a battery that is used to keep the system clock counting and the user settings saved in your motherboard’s circuitry. Over time, the battery can run out of energy and require replacing. These batteries are style CR2032 and are very easy to replace.

The instructions for replacing the battery simply ask you to open the case and locate the battery (it is contained on the motherboard, the circuit board all the cables/CPU plugs in to). Remove the battery by pulling the battery release lever and put a new battery in its place.
