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 support.toshiba.com.
If the problem is with an optical data disc, 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 optical disc drive itself. For additional
information see “You press the disc eject button, but the drive tray
does not slide out.” on page 155.
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.
