Battery
The battery that comes with your computer provides power to the real-time clock and has a lifetime of
about three years. When replacing the battery, use a battery equivalent to the battery originally installed
on the computer. The computer comes with a 3-volt lithium coin cell battery.
NOTE:
The lifetime of the lithium battery can be extended by plugging the computer into a live
AC wall socket. The lithium battery is only used when the computer is NOT connected to AC power.
WARNING!
This computer contains an internal lithium manganese dioxide battery. There is a
risk of fire and burns if the battery is not handled properly. To reduce the risk of personal injury:
Do not attempt to recharge the battery.
