When the computer cannot restore from
hibernation
To resolve a low-battery condition when the computer lacks the
power to restore from hibernation:
1. Insert a charged battery pack or plug the computer into
external power.
2. Restore from hibernation by pressing the power button.

Calibrating a battery pack

Three steps are involved in calibrating a battery pack: fully
charging, fully discharging, and then fully recharging.

When to calibrate

Even if a battery pack is heavily used, it should not be necessary
to calibrate it more than once a month. It is not necessary to
calibrate a new battery pack. Calibrate a battery pack under the
following conditions:
■
When battery charge displays seem inaccurate
■
When you observe a significant change in battery run time
■
When the battery pack has been unused for one month
or more
