CD problems
This section provides solutions to CD-related problems.
A CD or DVD does not work
Solutions:
• If you have multiple CD or DVD drives installed (or a combination of CD and DVD drives), try inserting the
disc into the other drive. In some cases, only one of the drives is connected to the audio subsystem.
• Ensure that the disc is inserted correctly, with its label up.
• Ensure that the disc you are using is clean. To remove dust or fingerprints, wipe the disc clean with a soft
cloth from the center to the outside. Wiping a disc in a circular motion might cause loss of data.
• Ensure that the disc you are using is not scratched or damaged. Try inserting another disc that you
know is good. If you cannot read from a known-good disc, you might have a problem with your optical
drive or the cabling to your optical drive. Ensure that the power cable and signal cable are securely
connected to the drive.
Unable to use a bootable recovery medium, such as the Product Recovery CD, to
start the computer
Solution: Ensure that the CD or DVD drive is in the startup sequence before the storage drive. Refer to
"Selecting a temporary startup device" on page 62 for information on viewing and changing the startup
sequence. Note that on some models the startup sequence is permanently set and cannot be changed.
DVD problems
This section provides solutions to DVD-related problems.
Black screen instead of DVD video
Solutions:
• Restart the DVD player program.
• Try a lower screen resolution or color depth.
• Close any open files, and then restart the computer.
DVD movie does not play
Solutions:
• Ensure that the disc surface is clean and not scratched.
• Check the disc or package for regional coding. You might need to purchase a disc with coding for the
region where you are using the computer.
No audio or intermittent audio while playing a DVD movie
Solutions:
• Check the volume control settings on the computer and on your speakers.
• Ensure that the disc surface is clean and not scratched.
