Use only the computer connected to an AC power source or optional TOSHIBA Battery charger to charge the battery pack. Never attempt to charge the battery pack with any other charger.

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 or 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 DC IN/Battery indicator glows green or Battery indicator glows white.

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 Taskbar

Via the Battery Status in the Windows Mobility Center window

You should wait at least 16 seconds after turning on the computer before trying to monitor the remaining operating time. This is because the computer needs this time to check the battery's remaining capacity and then calculate the remaining operating time, based on this together with the current power consumption.
