or auto/airline) has no
power from the AC outlet,
airplane seat jack, or the car's
cigarette lighter.
The Power adapter (AC or
auto/airline) is faulty.
The power management
parameters are set for auto
timeouts which are too short
for your operating needs.
You are operating on battery
power only and have ignored a
low battery alarm until the
batteries are all at the dead
battery state and your machine
has gone into Dead Battery
Suspend mode.
You have a battery failure.
Your power adapter has failed
or lost its power source.
The installed batteries
are dead.
No batteries are installed.
The batteries are
improperly installed.
Your installed batteries
are faulty.
You are running an application
that uses a great deal of power
due to frequent hard drive
access or DVD/CD-ROM
access, use of a modem card
or a LAN PC card.
The power savings features
may be disabled.
Possible Solutions
Move the AC cord to a different outlet, check for
a line switch or tripped circuit breaker for the AC
outlet. If you are using an auto/airline adapter in
a car make sure the ignition switch is in the On or
Accessories position.
Try a different Power adapter or install a charged
optional second battery.
Press any button or key on the keyboard, or move
the mouse to restore operation. If that fails, push the
Power and Suspend/Resume button. Check your
power management settings, or close your applica-
tions and go to the Power Savings menu of the setup
utility to adjust the timeout values to better suit
your operation needs.
Install a power adapter and then push the Power and
Suspend/Resume button. (See Power Sources on
page 33 for more information)

Status Indicator panel, and replace or remove
any batteries that are shorted. (See Status Indicator

application when at all possible.

settings in the Power Savings menu and adjust
according to your operating needs.
