CD or DVD drive does not function.
Please verify the following:
• Joybook 5000 is turned on, and the CD or DVD discs 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 disc plays shows that the optical
drive may be deformed, and Joybook 5000 needs to be repaired. If the
disc tray does not open after the eject button is pressed, insert a pin
into the Emergency Eject hole near the eject button to force the tray
out.
DVD movies do not play.
The region code of the DVD inserted must match that of the DVD
playback software. This region code can be set up to five times. If this
limit has not been reached, a prompt will appear that will allow you to
change the region code of the software to match that of the movie.
Otherwise, you can only play back DVDs with the same region code as
the last DVD played back successfully.
