Question

Quizplus · Accepted Answer

The small battery on the motherboard powers the CMOS (Complementary Metal-Oxide-Semiconductor) memory chip that stores the configuration settings for the system BIOS. If the battery dies, the configuration information is lost and needs to be entered and saved again using the System BIOS. The BIOS itself does not need to be replaced, nor does the entire motherboard.
