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 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 can not 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, then Control Panel, then System, and then Device Manager. 
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 it for at least one hour.
My optical drive tray does not open.
Make sure the notebook is turned on.
Press the Eject button on the optical drive.
If the Eject button does not work, open the tray by inserting a sharp, pointed 
object (such as a paper clip) in the hole to the right of the Eject button.
I cannot use Digital Video (DV) devices. The message “DV equipment seems to 
be disconnected or turned off” appears.
Check that the DV device is turned on and that the cables are properly 
connected.
If you are using multiple i.LINK
®*
 devices, the combination of the 
connected devices may cause unstable operation. In this case, turn off your 
notebook and all connected devices. Disconnect the devices that are not in 
use. Check the connections for each device, then restart your notebook.
