Troubleshooting DVDs and CDs
How do I maintain DVDs?

Avoid touching the surface of the disc with your fingers. Fingerprints and dust on the surface of the disc may cause
reading errors.
 To clean the disc, hold the edge of the disc, and use a soft cloth to wipe the surface from the center out. If the disc
is badly soiled, moisten a soft cloth with water, wring it out well, and use it to wipe the surface of the disc from the
center out. Wipe off any remaining moisture with a dry, soft cloth.

Do not clean the disc with solvents (such as benzine, thinner, commercially available cleaners, or anti-static spray),
which may damage the disc.
 Do not drop or bend the disc.
Why does my computer stop responding when I try to read a disc?
The disc your computer is trying to read may be dirty or damaged. Restart the computer, and eject the disc from the optical
drive. Examine the disc for dirt or damage. If the disc is dirty, see
How do I maintain CDs and DVDs? for instructions on how
to clean it.
Why won't the optical drive tray open?

Make sure the computer is on.
 Press the Eject button on the optical drive.
 If the Eject button does not work, open the tray by inserting a thin, straight object (such as a paper clip) in the hole
to the right of the Eject button.
Why isn't the optical drive playing my CD or DVD properly.
 Make sure the disc label is facing up.
 If the disc requires software, make sure the software is installed according to the manufacturer's instructions.

A dirty or damaged disc may cause the computer to stop responding while it tries to read the disc. If necessary,
restart the computer, remove the disc, and check the disc for dirt or damage.

If you see video but cannot hear audio, follow these steps:
 Make sure your optical drive does not have the mute setting enabled.
 Check the volume setting in the audio mixer.

If you are using external speakers, check the volume settings, and then check the connections between
your external speakers and the computer.

Click Start on the Windows
®
taskbar, and click Settings , then Control Panel , and System . Select the
Hardware tab, and click Device Manager . Make sure the correct driver software is properly installed.
 Do not use adhesive labels to identify the CD. The label may come off while the disc is in use in the optical drive and
cause the drive to malfunction.

If a region code warning appears when you try to use your optical drive, it may be that the DVD you are trying to
play is incompatible with the optical drive. Verify the region code listed on the DVD package.
 Condensation may cause the computer to malfunction. If this occurs, do not use it for at least one hour.
Why did the computer (LCD) screen go blank?

Your computer screen may go blank if the computer has lost power or is in a power saving mode (Standby or
Hibernate).
 Make sure the computer is plugged into a power source and is on. The power indicator on the computer will
be on if the computer is on.
