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 battery pack. You can purchase additional battery packs
for extended use of the computer away from an AC power source.
Before you remove the battery pack, set the computer to Hibernation
mode or save your data and shut down the computer. Do not change the
battery pack while the AC adaptor is connected.
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.
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 universal 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 indicator may not indicate a
low battery condition.
