Procedure 1 
Audio CD check 
First, insert an audio CD into the CD/DVD drive. If it works, the problem is not with the 
drive. Go to Procedure 3. If the audio CD does not work, go to Procedure 2. If the CD/DVD 
LED on the front panel does not light when the disc is played and the drive gives no response, 
go straight to Procedure 3. 
Procedure 2 
Drive cleaning check 
Insert a CD/DVD drive-cleaning disk into the drive clean according to the drive-cleaning 
product instructions. If the problem persists, go to Procedure 3. 
Procedure 3 
Software check 
Ensure that the appropriate driver has been installed on the computer for the CD/DVD drive. 
Procedure 4 
Diagnostic test 
The audio test program stored in the Diagnostics Disk will test the drive’s ability to play an 
audio CD. See Chapter 3 for details. 
If any errors occur while executing the diagnostic program, go to Procedure 5.
