I've an HP laptop with media keys. The primairy action F2 button is to dim screen, F7 is pauze current song, F8 next song etc, F11 mute.

When I want to use the real function of an Fx button I have to press the Fn button (between ctrl and super button) at the same time. So to go fullscreen I've to press Fn + F11 at the same time.

How can I revert this? So fo that F11 I go fullscreen and Fn + F11 mutes my sound?

You'll have to change the setting in the BIOS:

When you computer is booting, press F10 to access BIOS settings.

Navigate to:

System Configuration

and set:

Action Keys Mode



Save and exit.
