Battery charging notice

The battery may not begin charging immediately 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, you should charge it at room temperature of between 5° to

35°C (41° to 95°F).

The battery is nearly completely discharged. In this instance you should

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 cases you should follow the steps as detailed below:
1. Fully discharge the battery by leaving it in the computer with the power

on until the system automatically turns itself off.

2. Connect the AC adaptor to the DC IN 19V jack of the computer, and to

a wall outlet that is supplying power.

3. Charge the battery until the Battery indicator glows green.
Repeat these steps two or three times until the battery recovers normal

capacity.

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
