Battery charging notice

The battery may not charge right away under the following conditions:
■
The battery is extremely hot or cold. If the battery is extremely hot, it
might not charge at all. To ensure the battery charges to its full capacity,
charge the battery at room temperature of 10° to 30°C (50° to 88°F).
■
The battery is nearly completely discharged. Leave the AC adaptor
connected for a few minutes and the battery should begin charging.
The Battery indicator may show a rapid decrease in battery operating time
when you try to charge a battery under the following conditions:
■
The battery has not been used for a long time.
■
The battery has completely discharged and been left in the computer for
a long time.
■
A cool battery is installed in a warm computer.
In such case, follow the steps below.
1. Fully discharge the battery by leaving it in the computer with the power
on until the power automatically shuts off.
2. Connect the AC adaptor to the DC IN 15V jack of the computer,
and the AC adaptor into power outlet.
3. Charge the battery until the Battery indicator glows green.
Repeat these steps two or three times until the battery recovers normal
capacity.
Leaving the AC adaptor connected will shorten battery life. At least once a
month, run the computer on battery power until the battery is fully
discharged, then recharge the battery.
