A lithium battery on the motherboard provides backup
power for the PC's timekeeping capability. The battery
has an estimated life expectancy of seven years.
When the battery starts to weaken, the date and time
may be incorrect. If the battery fails, replace it with a
CR2032 lithium battery (3 volt, 220mAH rating) or an
equivalent battery.
WARNING: There is danger of explosion if
the battery is incorrectly replaced. Replace
only with the same, or equivalent, type of
battery. Discard used batteries according
to the manufacturer's instructions.
