107 - Troubleshooting
Possible Solutions
Verify that your adapter is connected correctly. See "Power
Sources" on page 67.
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.
Press any button on the keyboard, or move the mouse to
restore operation. If that fails, push the Power/Sus-
pend/Resume button. Check your power management set-
tings, or close your applications and go to the Power Options
located in the Control Panel to adjust the timeout values to
better suit your needs.
Install a power adapter, then push the Power/Sus-
pend/Resume button. See "Power Sources" on page 67.
Verify the condition of the battery using the Status Indicator
panel. If the battery is shorted, replace or remove it. See
"Status Indicator Panel" on page 30.
Make sure the adapter is plugged in and the outlet has
power.
Replace the battery with a charged one or install a power
adapter.
Verify that the battery is properly connected by re-installing it.
