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.

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°C to
35°C (41°F 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 DC IN/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.

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 DC IN/Battery indicator glows white.

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