NOTE: The charging time when the computer is on is affected by ambient

temperature, the temperature of the computer and how you use the

computer. If you make heavy use of external devices, for example, the

battery might scarcely charge at all during operation. Refer also to the

section Maximizing battery operating time.

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 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

until the power automatically shuts off.

2. Plug in the universal AC adaptor.

3. Charge the battery until the Battery indicator glows green.

Repeat these steps two or three times until the battery recovers normal capacity.

NOTE: Leaving the universal 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.
