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. Pressing [F9] repeatedly
while holding [Fn] will increase the volume of your LIFEBOOK.
The software volume control is
set too low.
Manually adjusting the volume using the keyboard hot keys should dynamically
adjust the volume (see above). If that doesn’t work, adjust the sound volume con-
trol settings in your software or application.
Headphones are plugged into
your LIFEBOOK.
Plugging in headphones disables the built-in speakers. Remove the headphones.
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. Pressing
the [F3] key while holding the [Fn] key will also toggle the audio on and off.
Hard Drive Problems
You cannot access your hard drive. Wrong drive designator was
used when a bootable disc
was used to start the system.
Verify drive designator used by application is in use by the operating system.
When the operating system is booted from a CD, drive designations are
automatically adjusted.
