If you will not be using your Notebook for an extended
Tip
period of time, Compaq recommends that you unplug the
electrical cord from the outlet and remove the battery while your
Notebook is not in use.
A low-battery condition exists
when the battery has less than 10
percent of its power remaining.
This section will show you how
to correct a low-battery condition
and what to do if your Notebook
loses all battery power.
When your Notebook loses all
battery power, it begins Hibernation, a process that cannot be
interrupted. If Hibernation has begun, you must allow your
Notebook to finish saving your information and shut off
automatically before you try to correct the low-battery condition.
The availability of an AC wall outlet will determine which
solution you should use to correct a low-battery condition.
Use one of the following options:
Connect the AC Adapter
Replace the Drained Battery with a Charged One
Suspend Your Work
