Power and Power-Up Modes
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.
No light 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.
