Charging the battery
When the power in the battery pack becomes low, the
DC IN/Battery
indicator flashes amber to indicate that only a few minutes of battery power
remain. If you continue to use the computer while the
DC IN/Battery
indicator flashes, the computer enters Hibernation Mode so that you do not
lose any data, and automatically turn itself off.
You must recharge the battery pack when it becomes discharged.
Procedures
To recharge a battery pack, connect the AC adaptor to the DC IN 19V jack
and plug the other end into a working outlet. The
DC IN/Battery
indicator
glows amber while the battery is being charged.
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.

The following table shows the approximate time required to charge an

Note that charging time will vary depending on the ambient
temperature, the temperature of the computer, and how the computer
is being used. For example, if you make heavy use of external devices
powered by the computer, or if the computer's internal storage drive is
being accessed frequently by an application, the battery might
scarcely charge at all during operation.
Charging notice
The battery might 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, 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, leave the
AC adaptor connected for a few minutes and the battery should begin
charging.
