Chapter 6. Solving Problems

Computer and Dock I problems can be caused by your computer, the Dock I, or both. To simplify diagnosing problems, isolate your computer and diagnose it first. Then test the Dock I with the computer attached. The diagnostic program on your computer diagnoses the Dock I and the computer when attached. Many problems can be diagnosed and solved with the assistance of the self-tests and the diagnostics programs of your computer.

By using the diagnostics 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 diagnostics 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 I.
