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

efficiently over the expected life of the battery and the Battery LED may not 

indicate a low-battery condition.

data and the real time clock and calendar stop working. The following 

message appears when you turn on the power:
