Possible Solutions
Check the Status Indicator Panel to verify the pres-
ence and condition of the battery. (See Status Indi-
cator Panel on page 13 for more information) Use an
AC adapter to operate until a battery is charged or
install a charged battery.
Verify that your adapter is connected correctly. (See
Power Sources on page 25 for more information)
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.
Verify the condition of the batteries using the Status
Indicator Panel, and replace or remove any batteries
that are shorted. (See Status Indicator Panel on
page 13 for more information)
Press any button on the keyboard, or move the
mouse to restore operation. If that fails, push the
Power/Suspend/Resume button. Check your power
management settings, or close your applications and
go to the Power Options menu of the setup utility to
adjust the timeout values to suit your needs.
Install a power adapter or a charged battery, then
push the Power/Suspend/Resume button. (See Power
Sources on page 25 for more information)
Make sure the adapter is plugged in and the outlet
has power.
