Care and use of the battery pack
This section provides the important safety precautions in order to handle
your battery pack properly.
Refer to the enclosed Instruction Manual for Safety and Comfort for
detailed precautions and handling instructions.
The battery pack can explode if not replaced, used, handled or
disposed of properly. Use only batteries recommended by TOSHIBA
as replacements.
Charge the battery pack only in an ambient temperature between 5
and 35 degrees Celsius. Otherwise, the electrolyte solution might leak,
battery pack performance might deteriorate and the battery life might
be shortened.
Charging the batteries
When the power in the battery pack becomes low, the DC IN/Battery
indicator will flash 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 will enable Hibernation Mode so that you do
not lose any data, and automatically turn itself off.
You must recharge a 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
will glow amber while the battery is being charged.
Charging Time
Refer to User Information Guide about Charging time.

should leave the AC adaptor connected for a few minutes and the
