Determining current
charge
The battery has lighted indicators that show,
when the computer is on, the charge remaining
in the battery. The following table shows how to
interpret the indicators.
Charging the battery
in the computer
Follow these steps to charge the battery in the
computer.
1. Insert the battery into the computer.
2. Plug in the AC adapter.
3. Connect the computer to the AC adapter.
4. Allow to charge 3 to 6 hours.
Note:
If you have both batteries installed in the
computer, it will take longer to charge the
batteries, since the batteries charge in parallel.
Charging the battery
in an external
battery charger
An optional external battery charger allows you
to charge a battery while you are using the
computer. Use only the battery charger
designed for your computer. Follow the
directions that come with the external battery
charger. To order an optional battery charger,
