When the AC power cord is not connected, the computer’s main power
source is a removable lithium-ion Battery Pack, also referred to in this
manual as the Battery. You can purchase Battery Packs for extended use
of the computer away from an AC power source.
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 battery recommended by
TOSHIBA as replacements.
Do not remove the battery pack while the computer is in Standby mode.
Data is stored in RAMs, 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
program in memory. If the battery pack is completely discharged, Standby
mode does not function and the computer loses all data in memory.
To ensure that the Battery Pack maintains its maximum capacity, operate
the computer on battery power at least once a month until the Battery
Pack is fully discharged. Refer to
Extending battery life in this chapter for
procedures. If the computer is continuously operated on AC power,
through an AC adaptor for an extended period, more than a month, the
battery may fail to retain a charge. It may not function efficiently over the
expected life of the battery and the Battery LED may not indicate a low-
battery condition.
