When the computer is powered off in Resume mode, and the AC adaptor
in not connected, the main battery pack and optional secondary battery
pack supply power to maintain data and programs in memory. If the
battery pack(s) is completely discharged, Resume does not function and
the computer loses all data in memory.
The following message appears when you turn on the power:
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, either
through an AC adaptor or a docking station 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.
Secondary battery (option)
An optional secondary battery can be installed in the Slim Select Bay to
increase your battery operating time. Note the caution on Resume mode
in the previous section Main battery.
The secondary 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.
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.
If the RTC battery becomes completely discharged, the system loses this
data and the real time clock and calendar stop working. The following
message appears when you turn on the power:
The computer's RTC battery is a lithium ion battery and should be
replaced only by your dealer or by a TOSHIBA service representative. The
battery can explode if not properly replaced, used, handled or disposed
of. Dispose of the battery as required by local ordinances or regulations.
