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 that you can pass on to a service technician. You
might also need to refer to your computer, operating-system, or sound-adapter
documentation.
Review the following list for any problem description that might fit your
situation.
v Your computer or CD-RW/DVD-ROM Combination Drive does not
operate correctly, or the busy indicator light does not come on.
Take the following actions:
1. Check that the disc is loaded with the label side up.
2. Check that all devices are properly connected to the computer and to the
electrical outlet.
3. Turn off the computer, unplug the cables for your computer and all
attached devices, and remove the computer cover.
4. Check that all power and IDE cables are securely attached. Disconnect
the IDE cable and check for bent or misaligned pins. If you do not find
any problems, reconnect the interface cable. Replace the computer cover,
and reattach all cables and power cords. Turn on the computer, restart
the operating system, and attempt to open the loading tray by pressing
the Open/Close button. If the tray fails to open and the Busy indicator
does not light, turn off the computer and try using another 4-pin dc
power cable.
5. Check that the color-coded edge on the IDE cable aligns with pin 1 on
the IDE connector and is closest to the power cable on the
CD-RW/DVD-ROM Combination Drive. See “Step 6. Attaching the
cables to the drive” on page 1-7.
6. Check the CD-RW/DVD-ROM Combination Drive and any other device
on the IDE cable for the proper settings.
7. If the middle connector on the IDE cable is attached to the IDE connector
on the system board, remove the connector and reattach the cable. If
there is only one device on the IDE connector, attach the connector at one
end of the cable to the IDE connector and the connector at the other end
to the device, leaving the middle connector (if there is one) open.
If there are two devices on the IDE connector, attach the connector at one
end of the cable to the IDE connector. If there is a hard disk drive, attach
it to the connector at the other end of the cable, and attach the
CD-RW/DVD-ROM Combination Drive to the middle connector.
