Troubleshooting Your LifeBook

Troubleshooting

There may be occasions when you encounter simple setup or operating problems that you can solve on

the spot, or problems with peripheral devices that can be solved by replacing the device. The

information in this section helps you isolate and resolve some of these straightforward issues and

identify failures that require service.

Identifying the Problem

If you encounter a problem, go through the following procedure before pursuing complex

troubleshooting:

1 Turn off your LifeBook notebook.

2 Make sure the AC adapter is plugged into your 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 notebook. Make sure it has been off at least 10 seconds before you turn it back on.

6 Go through the boot sequence.
