If Something Goes Wrong
Sound system problems
Never use a pencil to press the manual eject button. Pencil lead can 
break off inside the computer and damage it.
Some discs run correctly but others do not.
Check that the type of disc you are using is compatible with your 
optical disc 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 
application’s needs.

Sound system problems
No sound is coming from the computer’s speakers.
Adjust the volume control.
Try pressing the 
F11
 key 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.
Printer problems
This section lists some of the most common printer problems.
The printer will not print.
Check that the printer is connected to a working power outlet, 
turned on and ready (on line).
Check that the printer has plenty of paper. Some printers will not 
start printing when there are just two or three sheets of paper left in 
the tray.
