Troubleshooting

English

There is no audio coming from my computer.

Check the following:

• The volume may be muted. In Windows, look at the volume

control icon on the taskbar. If it is crossed-out, click on the icon

and deselect the Mute option.

• The volume level may be too low. In Windows, click on the volume

control icon on the taskbar, and then use the slider control to

increase the volume level.

• If headphones are connected to the headphone jack on the

computer, your computer's built-in speakers will be turned off.

My external microphone does not work.

Check the following:

• Make sure that the external microphone is properly plugged into

the microphone-in jack on the computer.

• Make sure that the volume is not muted or set too low.

I can't eject the optical drive tray with my computer turned off.

The computer needs to be turned on for the optical drive eject button

to function. If you need to eject the optical drive tray when the

computer is turned off, push a straightened paper clip into the optical

drive emergency eject hole. See “Ejecting the optical drive tray” on

page 26 for more information.

The keyboard does not respond.

Try attaching an external USB keyboard to one of your computer's USB

ports. If it works, the internal keyboard might have become

disconnected. Contact your dealer or an authorized service center.

The floppy disk drive cannot read a diskette.

Check the following:

• Make sure the diskette is properly inserted in the floppy disk drive.

• Make sure that the diskette is formatted.

• Try to read a second diskette. If this works, then the first diskette

might have a problem.

• If the diskette is not the cause of the problem, then the drive head

might be dirty. Clean it using a drive head cleaning kit.
