Battery types
The computer has three types of batteries:
■
Battery pack
■
2nd battery pack (option)
■
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 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.
■
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 main 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.
