    Hello guys,

    Sorry if the question has been asked before, but I've been looking for a solution for 3 days to no avail.

    I recently upgraded a buddy's M17X r2 to windows 8, and after a myriad of AMD drivers (Stock, 13.1 to 13.6 beta) I still cannot get the brightness settings (Fn+F4 & Fn+F5) to work in-windows. Oddly enough it works when I have a fresh install w. no drivers or when in BIOS. Hopefully somebody here can shed some light on this.

    Thanks in advanced.
