CD or DVD does not function.
Please verify the following:
• The computer is turned on, and the CD or DVD disks are properly
inserted in the center of the disk tray in the optical drive.
• The DVD disk tray is closed.
Noise from the optical drive when the disk plays shows that the optical drive
may be deformed, and the computer needs to be repaired. If the disk tray
does not open after the Eject button is pressed, insert a pin into the Emer-
gency Eject hole to force the tray out.
DVD movies will not play.
The region code of the DVD inserted must match that of the DVD playback
software used. This region code can be set up to five times. If you have not
reached this limit, a prompt will appear that will allow you to change the
region code of the software to match that of the move. Otherwise, you can
only play back DVDs with the same region code as the last DVD played back
successfully.
