Audio Problems

There is no sound coming

from the built-in speakers.

The volume is turned

too low.

Adjust the volume control on your notebook and operating system.

Use the [Fn+F9] key combination on your keyboard. Pressing [F9]

repeatedly while holding [Fn] will increase 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 headphones.

Software driver is not

configured correctly.

The Audio Driver may be installed or reinstalled by using the Driv-

ers and Applications CD that came with your LifeBook. Refer to

your application and operating system documentation for help.
