Resolving Low-Battery Conditions
Ä
CAUTION:
To prevent problems when restoring from hibernation: If the
notebook has reached a critical low-battery condition and has begun to
initiate hibernation, do not restore power until hibernation is complete.
When hibernation is complete, the power/standby lights are turned off.
To resolve a low-battery condition:
■
If external power is available, connect the notebook to the
external power source.
■
If a charged battery pack is available, shut down the notebook
or initiate hibernation, insert the charged battery pack, and
then turn on the notebook.
■
If no power source is available,
save your work and initiate
hibernation or shut down the notebook.
Calibrating a Battery Pack
When to Calibrate
Even if a battery pack is heavily used, calibration should be
necessary only once a month. You do not have to calibrate a new
battery pack before first use.
Calibration does not usually increase battery run time, but it can
increase the accuracy of battery charge displays, especially under
the following conditions:
■
When the battery pack has been unused for one month
or more.
■
When the notebook has been running primarily on
external power (and rarely on battery power) for more
than one month.
