HP Pavilion home PC
Replacing the Battery
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 manufacturers
instructions.
To replace the battery:
1 Remove the side panel that has the
thumbscrews. See page 4.
2 Gently lay the PC on its side.
3 Remove any cabling, if necessary, to reach the
battery.
4 Remove any memory modules, if necessary, to
reach the battery.
5 With a flat screwdriver, press the metal latch
that holds the battery in its socket away from
the battery. The battery will pop out.
6 Install the new CR2032 battery in the socket,
with the positive (+) side facing up.
