In a computer, a '''CMOS battery''' is tied to the [[motherboard]], the coordinating mainframe of any [[Windows|PC]] or [[Macintosh|Mac]] computer. The battery is responsible for retaining system memory, and especially date and time information, when the system is powered down. Should the CMOS battery fail, the [[BIOS]] (Basic Input-Output System), which coordinates baseline system processes, will likely wipe, as well.
In short, do not remove your CMOS battery.
