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 of your 
notebook.
The software volume 
control is set too low.
Manually adjusting the volume (i.e., using the Volume button or 
keyboard "hot keys") should dynamically adjust the volume of the 
operating (see above). If that doesn’t work, adjust the sound vol-
ume 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 
Drivers and Applications CD that came with your LifeBook. Refer 
to your application and operating system documentation for help.
The speakers have 
been muted using the 
Volume icon in the sys-
tem 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. Pressing the [F3] key while holding the 
[Fn] key will also toggle the audio on and off.
Optical Drive Problems
LifeBook notebook fails to 
recognize DVD/CD-
RW/CD-ROM’s.
The disc is not pushed 
down onto raised center 
circle of the drive.
Open optical drive tray and re-install the disc properly.
Optical drive tray is not 
latched shut.
Push on the front of the optical drive tray until it latches. If that 
doesn’t work, pull out the modular drive latch to remove the device 
from the bay, then re-insert the drive until it latched; this ensures 
that the drive is properly seated. 
DVD Player software 
not installed properly.
Install DVD Player software. (
