America) DVDs. You can change this setting (refer to 
), but only a very 
limited number of times.
If the problem is with a data CD or DVD, refer to the software’s 
documentation and check that the hardware configuration meets 
the program’s needs.
The disc will not come out of the drive when you click the 
eject button on the screen.
Press the button on the CD-ROM or DVD-ROM drive itself.
Sound system problems
You don’t hear any sound from the computer.
Adjust the volume control. There is a volume control dial on the 
computer, a volume control feature in the Windows Control Panel 
(“Sounds”), or it might be muted. There may also be a volume 
control on your speakers or headphones or in your audio 
application.
If you are using an external microphone or speakers, check that 
they are securely connected to your computer.
