Power indicator
Check the Power indicator to determine the power status:
White
Indicates power is being supplied to the computer 
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.

Under any other conditions, the indicator does not 
light.
Battery types
The computer has the following batteries:
n
Battery pack ( 6cell or 12cell depending on the model.)
n
Real Time Clock (RTC) battery
n
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.
n
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.
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.
