Audio Problems
There is no sound coming from
the built-in speakers. The volume is turned too low. Use the [Fn+F9] key combination on your keyboard to control the volume. Press-
ing [F9] repeatedly while holding [Fn] will increase the volume of your note-
book. [Fn+F8] will lower the volume.
The software volume control
is set too low. Manually adjusting the volume (i.e. keyboard "hot keys") should dynamically
adjust the volume of the operating (see above). If that doesn’t work, adjust the
sound volume control settings in your software or application.
Headphones are plugged into
your notebook. Plugging in headphones disables the built-in speakers, remove the head-
phones.

The audio driver may be installed or reinstalled by downloading it from the
Fujitsu support site (see “Maintaining Latest Configuration” on page 10). Refer
to your application and operating system documentation for help.
The speakers have been
muted using the Volume icon
in the system tray. Click on the Volume icon in the tool tray on the bottom right of the screen. (It
looks like a speaker). If the Mute box is checked, click on it to uncheck it. You can
also use the [Fn+F3] key combination to toggle the volume on and off. Pressing
[F3] while holding [Fn] will toggle the audio mute.
