I am using a Q702 and am facing a really big problem. My hotkeys FN + F6 (brightness down) and FN + F7 (brightness up) won't work as expected. When I click FN + F6 the 6th program of my quick launch bar is opened. When I click FN + F7 it is the 7th program that gets opened.
All the other function keys work as expected, e.g. FN + F4 = touchpad disabled. Only those mentioned above show this strange behaviour. I have already installed all drivers I could find or at least I hope so, but it won't work.
