The computer has five types of batteries:

■ High capacity battery pack (option)
■ Real Time Clock (RTC) battery
Battery pack
When the AC adaptor is not connected, the computer’s main power source
is a removable lithium ion battery pack, also referred to in this manual as
the main battery. You can purchase additional battery packs for extended
use of the computer away from an AC power source.
Do not change the battery pack while the AC adaptor is connected.
Before you remove the battery pack, save your data and shut down the
computer, or set the computer to Hibernation Mode. While entering
Hibernation Mode, the computer saves the contents of memory to the hard
disk drive. However, for safety sake, it is best to save your data manually.
■ The battery pack is a lithium ion battery, which can explode if not
properly replaced, used, handled or disposed of. Dispose of the battery
as required by local ordinances or regulations. Use only batteries
recommended by TOSHIBA as replacements.
■ Always use the battery pack supplied as an accessory or an equivalent
battery pack specified in the User's Manual. Other battery packs have
different voltage and terminal polarities. Use of non-conforming battery
packs could generate smoke or cause fire or rupture, possibly resulting
in serious injury.
■ Always dispose of used battery packs in compliance with all applicable
laws and regulations. Put insulating tape, such as cellophane tape, on
the electrode during transportation to avoid a possible short circuit, fire
or electric shock. Failure to do so could possibly result in serious injury.
■ Do not remove the battery pack while the computer is in Standby
Mode. Data is stored in RAM, so if the computer loses power it will be
lost. When the computer is powered off in Standby Mode, and the AC
adaptor is not connected, the battery pack supplies power to maintain
data and programs in memory. If the battery pack is completely
discharged, Standby Mode will not function and the computer loses all
data in memory.
