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.

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.

use it for at least one hour.
