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:
1Turn off your LifeBook notebook.
2Make sure the AC adapter is plugged into your notebook and to an active AC power source.
3Make 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.
4Make 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.
