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.

and the computer is turned on.
Blinking orange Indicates power is being supplied to the computer
while the computer is in Sleep Mode. The indicator
turns on for one second and off for two seconds.
No light Under any other conditions, the indicator does not

■ 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 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 main battery pack supplies power to maintain
data and programs in memory. If the battery pack is completely
discharged, Sleep Mode does not function and the computer loses all
data in memory.
