Running the computer on battery power
Running the computer on battery power
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 “Maximizing
battery life” on page 110 for procedures. If the computer is
continuously operated on AC power, either through an AC adapter
or a docking station for an extended period, 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.
For more information on running your system on battery power,
consult “Running the computer on battery power” on
page 108.
Powering down the computer
When you power down the computer, you have three options to
choose from:
❖ Shut down, which powers off the computer
❖ Hibernation, which saves the current operating mode to the
hard disk and powers off the computer
❖ Standby, which saves the current operating mode to memory
and enters a low power mode
Each option has its advantages.
NOTE: Avoid turning off the power while a disk light on the
system indicator panel is on. Doing so may damage your
hard disk, diskette drive, DVD-ROM or
DVD-ROM /CD-RW multifunction drive.
