Upgrading and Servicing Guide
A lithium battery on the motherboard provides backup power for the computer
timekeeping capability. The battery has an estimated life expectancy of seven years.
When the battery starts to weaken, the date and time may become 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 it only with a battery of the same, or an equivalent, type. Discard
used batteries according to the manufacturer's instructions.
