Battery types

The computer has three types of batteries:
■
Battery packs – main, 2nd (option) and High capacity (option)
■
Real Time Clock (RTC) battery

Main battery

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.
■
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 AC adaptor
is not connected, the main battery pack and optional 2nd battery pack
supply power to maintain data and program in memory. If the battery
pack(s) 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.
