Qosmio G40
Battery types
The computer has two different types of batteries:
■
Battery pack
■
Real Time Clock (RTC) battery
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. You can purchase additional battery packs for extended use of
the computer away from an AC power source although you should not
change the battery pack while the AC adaptor is connected.
Before you remove the battery pack, save your data and shut down the
computer, or place the computer into Hibernation Mode. Please be aware
that, when placing the computer into Hibernation Mode, the contents of
memory will be saved to the hard disk drive, although for safety sake, it is
best to also save your data manually.
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 - please refer to
Extending battery life in this chapter for
details of the procedure.
If the computer is continuously operated on AC power through connection
to an AC adaptor for an extended period, for example more than a month,
the battery may fail to retain a charge, it may not function efficiently over its
expected life and the Battery indicator may not properly indicate a low-
battery condition.
■
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.
■
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 Sleep Mode.
Data is stored in RAM, so if the computer loses power it will be lost.
When the computer is powered off in Sleep 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,
Sleep Mode will not function and the computer loses all data in
memory.
