You turn on your LifeBook
notebook and nothing
seems to happen.

The power adapter has
no power from the AC
outlet, 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
On or Accessories position.
Your LifeBook notebook
turns off all by itself.
The power manage-
ment parameters are
set for auto timeouts
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.
