Audio problems

If no sound is audible

•If your model has a volume control, press the + (plus) button to increase the volume.

•Double-click the speaker icon on the taskbar (if present). Clear the Mute all checkbox if selected. If your model has an audio mute button, press it so the indicator light goes off.

•When you are operating your notebook in MS-DOS mode (for example, when running MS-DOS games), you may find that the sound does not operate properly. Use Windows applications for full use of sound capabilities.

If sound does not record

•Plug in an external microphone. The notebook does not have a built-in microphone.

•Check the software controls for recording sound. Select Start > All Programs > Accessories > Multimedia (or Entertainment) > Sound Recorder.

•In Volume Control, select Option > Properties, and make sure the microphone is enabled in the recording controls.
