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.

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 Serial ATA cables are securely attached. Disconnect the Serial ATA 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 15 PIN power cable.
