Power and Power-Up Modes
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.
High capacity battery pack (option)
An optional High capacity battery pack is installable instead of a main
battery pack. The connection method of High capacity battery pack is the
same as that of main battery pack.
■ Always use the battery pack supplied as an accessory or an equivalent
battery pack specified in the User's Manual. Other battery packs have
different voltage and terminal polarities. Use of non-conforming battery
packs could generate smoke or cause fire or rupture, possibly resulting
in serious injury.
■ Always dispose of used battery packs in compliance with all applicable
laws and regulations. Put insulating tape, such as cellophane tape, on
the electrode during transportation to avoid a possible short circuit, fire
or electric shock. Failure to do so could possibly result in serious injury.
■ 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 battery pack supplies power to maintain
data and programs in memory. If the battery pack is completely
discharged, Standby Mode will not function and the computer loses all
data in memory.
■ 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 supply 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.
■ When the High capacity battery pack is connected to the computer, do
not hold on only to the High capacity battery pack when lifting the
computer up.
The High capacity battery pack may separate from the computer,
causing it to fall and cause injuries.
