Appendix B. Problem solving

Computer problems can be caused by hardware, software, or user error. Using
the information in this section, you might be able to solve problems yourself or
gather helpful information you can pass on to a service technician. You might
also need to refer to your computer, operating-system, or audio-adapter
publications.
Problem descriptions
Review the following list for any problem descriptions that might fit your
situation.
Your computer or CD-ROM drive does not operate correctly
or the Busy indicator light does not come on.
Take the following actions:
1. Make sure that the CD is inserted with the label side up or facing out if the
drive is installed vertically.
2. Make sure that all devices are properly connected to the computer and the
electrical outlet.
3. Turn off the computer, unplug the cables from the electrical outlets for your

tray by pressing the Eject/Load button. If the tray fails to open and the
Busy indicator light does not display, turn off the computer and try
replacing the 4-pin dc power cable.
5. Make sure that the color-coded edge on the IDE cable aligns with pin 1 on
the IDE port and is closest to the power cable on the CD-ROM drive. See
"Step 6. Attaching the cables to the drive" on page 1-6.
6. Make sure that the IDE cable is connected to the correct IDE port
connection. See "Step 3. Selecting the IDE port" on page 1-4 for more
information.
7. Check the CD-ROM drive and any other device on the IDE cable for the
proper jumper configuration settings. See "Step 4. Setting the configuration
jumper" on page 1-5 for more information.
8. Check to see if the middle connector on the IDE cable is attached to the
IDE port on the system board. If it is, remove the connector and reattach
the cable correctly. The middle port is used only if you are connecting two
devices to the IDE port. If there are two devices on the IDE port, attach the
