If Something Goes Wrong
Resolving a hardware conflict
Some discs run correctly but others do not.
Check that the type of disc you are using is compatible with your 
optical drive. For more information regarding supported optical 
media formats, refer to the complete detail specifications for your 
computer at 
If the problem is with an optical data disc, refer to the software’s 
documentation and check that the hardware configuration meets the

eject button on the screen.

Sound system problems 
No sound is coming from the computer’s speakers.
Adjust the volume control.
Try pressing 
Fn + Esc
 to see if volume mute is disabled.
Check that the volume control on the computer is turned up.
If you are using external headphones or speakers, check that they 
are securely connected to your computer.
The computer emits a loud, high-pitched noise.
This is feedback between the microphone and the speakers. It 
occurs in any sound system when input from a microphone is fed to 
the speakers and the speaker volume is too loud. Adjust the volume 
control.
