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 ExpressCard 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.
