Power and Power-Up Modes
To ensure that the battery pack maintains its maximum capacity, operate
the computer on battery power at least once a month until the battery pack
is fully discharged. Refer to Extending battery life in this chapter for
procedures. If the computer is continuously operated on AC power, more
than a month, the battery may fail to retain a charge. It may not function
efficiently over the expected life of the battery and the Battery LED may not
indicate a low-battery condition.
Real time clock battery
The Real Time Clock (RTC) battery provides power for the internal real
time clock and calendar. It also maintains the system configuration.

data and the real time clock and calendar stop working. The following
message appears when you turn on the power:
