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 manufacturer’s instructions.
To replace the battery:
1Remove the side panel that has the thumbscrews. See page 99.
2Gently lay the PC on its side.
3Remove any cabling, if necessary, to reach the battery.
4Remove any memory modules, if necessary, to reach the battery.
5With a flat screwdriver, press the metal latch that holds the battery in its socket away from the battery. The battery will pop out.
6Install the new CR2032 battery in the socket, with the positive (+) side facing up.
