Troubleshooting

Your LifeBook notebook is sturdy and subject to few

problems in the field. However, you may encounter

simple setup or operating problems that you can solve

on the spot, or problems with peripheral devices, that

you can solve by replacing the device. The information

in this section helps you isolate and resolve some of

these straightforward problems and identify failures that

require service.

IDENTIFYING THE PROBLEM

If you encounter a problem, go through the following

procedure before pursuing further troubleshooting:

1. Turn off your LifeBook notebook.

2. Make sure the AC adapter is plugged into your Life-

Book notebook and to an active AC power source.

3. Make sure that any card installed in the PC Card slot

is seated properly. You can also remove the card

from the slot, thus eliminating it as a possible cause

of failure.

4. Make sure that any devices connected to the external

connectors are plugged in properly. You can also

disconnect such devices, thus eliminating them as

possible causes of failure.

5. Turn on your LifeBook notebook. Make sure it has

been off at least 10 seconds before you turn it on.

6. Go through the boot sequence.

7. If the problem has not been resolved, refer to the

Troubleshooting Table, that follows, for more

detailed troubleshooting information
