Sony PCG-FXA59 - Manual (Page 107)

My optical disc drive is not playing my CD or DVD properly.
 Check that the label of the disc is facing up.
 If the disc requires software, check that the software is installed according to the manufacturer's instructions.
 A dirty or damaged disc may cause the notebook to stop responding while it tries to read the disc. If necessary,
restart the notebook, remove the disc, and then check it for dirt or damage.
 If you see video but cannot hear audio, check all of the following:
 Check that 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 notebook.
 Click Start, Control Panel, Performance and Maintenance, System, and then select the Hardware tab. Click
Device Manager to open the Device Manager dialog box. Check that the correct drivers are installed
properly.
 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. Check the region code listing on the DVD packaging.
 Condensation may cause the notebook to malfunction. If this occurs, do not use the notebook for at least one
hour.
