CMOS battery
The CMOS RAM battery is commonly referred to as the "CMOS battery." It is typically a small coin-cell battery, often a CR2032 lithium battery, that powers the CMOS (Complementary Metal-Oxide-Semiconductor) memory. This memory stores BIOS settings and system time when the computer is turned off. If the CMOS battery fails, users may experience issues with system settings and time retention.

Chances are that the CMOS Battery on the motherboard is dead and needs to be replaced. Without this battery, the computer can not remember the CMOS settings when the power is turned off.
CMOS holds many of the boot parameters, such as what type and size of hard disk, the type and speed of the processor and other critical information. Many times the computer can still boot with a dead CMOS battery, but the information will not be available and will affect the process. Replace the battery then run through the setup procedure to save the values.
