       Troubleshooting Your LifeBook
Troubleshooting
There may be occasions when you encounter 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 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.
7
If the problem has not been resolved, refer to the Troubleshooting Table, that follows, for more detailed 
troubleshooting information.
