All Computers have a small battery to power the CMOS Non_volatle memory that stores the time, date, passwords(if used) and system setup. (This is NOT the main power battery used in a laptop) this is a semi-permanent battery (most often a quarter sized CR2032 in newer computers, but it could be a NiCad or other type). Think "large watch/clock battery." If it is dead then when the power is turned off there is no power to maintain the CMOS and everything reverts to the default time, DAte, and setup. This battery CAN be changed by a layman/user but is probably best done by a qualified technician.
