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.
