If I press either
Fn+F4 (which are supposed to be brightness down and up), it instead activates/deactivates the internal microphone (the same as
Fn+F8 does which is what it is supposed to do).
I read somewhere that it might have to do with 2 different keyboard drivers overriding the assigned keycodes. But I couldn't find anything about keyboard drivers in
Also, the keycodes for both
Fn+F4 are the same:
keycode 190 press | keycode 190 release
What options do I have to troubleshoot this? On Windows the keys work as expected, so I guess it is not a BIOS problem?
