Small Battery for the Real Time Clock
There is a small built-in battery pack that supplies power to the system
in order to maintain certain system information while the power is off.
If the computer is left without a power source for long period of time,
this battery will be exhausted and system information will be lost.
To avoid damage, only use replacement batteries
recommended by System provider. To prevent the loss of
data when the system loses power, do not remove the
battery pack while the power is on.
