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 5° to 35°C (41° to 95°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.
Monitoring battery capacity
Remaining battery power can be monitored using the following methods.
■ Clicking the battery icon on the task bar
■ Via the Battery Status in the Windows Mobility Center window
Please be aware that the charging time when the computer is on is
affected by ambient temperature, the temperature of the computer and
how you are using the computer - if you make heavy use of external
devices, for example, the battery might scarcely charge at all during
operation. Please refer to the section Maximizing battery operating time for
further information.
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.
