LifeBook P1600 Series Notebook
FUNCTION KEYS
Your system has 12 function keys, F1 through F12. The
functions assigned to these keys differ for each applica-
tion. You should refer to your software documentation
to find out how these keys are used. (Figure 2-16)
[Fn] Key
The [Fn] key provides extended functions for the
notebook and is always used in conjunction with
another key.
■
[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 32)
■
[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 moni-
tor only, and both built-in display panel and external
monitor.
