Charging the batteries
When the power in the battery pack becomes low, the Battery indicator
flashes orange indicating that only a few minutes of battery power remain.
If you continue to use the computer while the Battery
indicator flashes, the
computer enables Hibernation mode (so you don’t lose data) and
automatically turns off.
You must recharge a battery pack when it becomes discharged.
Procedures
To recharge a battery pack while it is installed in the computer, connect the
AC adaptor to the DC IN 15V jack and plug the other end into a working
outlet.
The Battery indicator glows orange when the battery is being charged.
Time
The following table shows the approximate time required to fully charge a
discharged battery.

Battery charging notice
The battery may not charge right away 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 the battery at room temperature of 10 ° to 30 °C (50 ° to 88 °F).
■
The battery is nearly completely discharged. Leave the AC adaptor
connected for a few minutes and the battery should begin charging.
The computer enters Hibernate mode only if Hibernation is enabled in two
places: the Hibernate tab in Power Options and Setup Action tab in
TOSHIBA Power Saver.
Use only the computer connected to an AC power source or the optional
TOSHIBA Battery charger to charge the battery pack. Never attempt to
charge the battery pack with any other charger.
