The battery is nearly completely discharged. Leave the universal 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
