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.
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.
Battery pack
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.
Real Time Clock battery
The Real Time Clock (RTC) battery provides power for the internal real
time clock and calendar. It also maintains the system configuration.
■ 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 Sleep Mode.
Data is stored in memory and will be lost if the computer loses power.
When the computer is powered off in Sleep Mode, and the AC adaptor
is not connected, the main battery pack supplies power to maintain
data and programs in memory. If the battery pack is completely
discharged, Sleep Mode does not function and the computer loses all
data in memory.
