notebook and nothing seems
to happen.

The power adapter (AC
or auto/airline) is not
plugged in properly.
Verify that your adapter is connected correctly.
See “Power
Sources” on page 48.
The power adapter (AC
or auto/airline) has no
power from the AC out-
let, airplane seat jack,
or cigarette lighter.
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

which are too short for
your operating needs.
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 applica-
tions and go to the Power Options Properties located in the Con-
trol Panel to adjust the timeout values to better suit your needs.
