CMOS (Complementary Metal Oxide Semiconductor) Battery
This small battery, located on your computer’s mainboard, provides battery backup and prevents BIOS data
loss when other power sources are not connected. The BIOS contains information on the computer's config-
uration, for example date, time, drives and memory. The CMOS battery charges when your computer is
connected to AC power.
The CMOS battery may discharge completely if the computer remains unused for approximately
two months. If this occurs you may need to enter the BIOS to reset the system date and time - other
settings should be detected automatically.
