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 tablet's RTC battery is a lithium battery and should be replaced
only by your dealer or by a TOSHIBA service representative. The
battery can explode if not properly replaced, used, handled or
disposed. Dispose of the battery as required by local ordinances or
regulations.
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 Battery indicator will
flash amber to indicate that only a few minutes of battery power remain. If
you continue to use the tablet while the Battery indicator flashes, the tablet
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
