Function Keys
Your LifeBook notebook has 12 function keys, F1 through F12. The functions assigned to these keys differ
for each application. You should refer to your software documentation to find out how these keys are used.
• [Fn+F3]: Pressing [F3] while holding [Fn] will toggle the Audio Mute on and off.
• [Fn+F4]: Pressing [F4] while holding [Fn] will toggle the built-in pointing device on and off. Note
that the [Fn+F4] combination only works if Manual Setting is selected in the BIOS. (See “Entering
the BIOS Setup Utility” on page 50)
• [Fn +F5]: Pressing [F5] while holding [Fn] allows you to toggle between video compensation and
no compensation. (Video compensation controls spacing on the display. When it is enabled,
displays with less than 1024 x 600 or 800 x 600 pixel resolution will still cover the entire screen.)
• [Fn+F6]: Pressing [F6] repeatedly while holding [Fn] will lower the brightness of your display.
Note that adjusting the brightness using the keyboard changes the system setting.
• [Fn+F7]: Pressing [F7] repeatedly while holding [Fn] will increase the brightness of the display.
• [Fn+F8]: Pressing [F8] repeatedly while holding [Fn] will decrease the volume of your system.
• [Fn+F9]: Pressing [F9] repeatedly while holding [Fn] will increase the volume of your system.
• [Fn+F10]: Pressing [F10] while holding [Fn] allows you to change your selection of where to send
your display video. Each time you press the combination of keys you will step to the next choice.
The choices, in order, are: built-in display panel only, external monitor only, and both built-in
display panel and external monitor.
