Battery types
The computer has two (2) types of batteries:
■ Battery pack
■ Real Time Clock (RTC) battery
Battery pack
When the AC adapter 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.
The battery is a disposable item. When its operation becomes short even
when fully charged, replace it with a new one.
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.
Green The power button will glow green while power is
being supplied and the computer is turned on.
The power indicator on the front of computer will
glow green when the computer is switched on.
Blinking amber Indicates power is being supplied to the
computer while the computer is in Sleep mode.
No light Under any other conditions, the indicator does
not light.
■ The battery pack is a lithium ion battery, which can explode if not
properly replaced, used, handled, or disposed. Dispose 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 Sleep Mode. In
this mode data is stored in memory, so if the computer loses power,
data will be lost.
■ Battery type (depending on the purchased model):
4-cell - PA3591U-1BAS, PA3591U-BRS
6-cell - PA3615U-1BAM, PA3615U-1BRM.
