Chapter 6. Solving Problems
Computer and Dock II problems can be caused by your computer,
the Dock II, or both. To simplify diagnosing problems, isolate your
computer and diagnose it first. Then test the Dock II with the
computer docked. The diagnostic program on your computer
diagnoses the Dock II and the computer when docked. Many
problems can be diagnosed and solved with the assistance of the
self-tests and the diagnostics programs of your computer.
By using the diagnostic programs on your computer, you may be
able to solve the problem yourself or provide information to the
service representative. Make a note of all error messages and be
prepared to give them to the service representative if you need to call
for service. If the diagnostic programs on your computer cannot be
loaded, refer to the troubleshooting charts and other information
supplied with your computer.
The troubleshooting charts and other information in this chapter will
help you determine what corrective action to take for the Dock II.
