I run a Asus Strix gaming laptop - model gl502vs, and for the most part it has not given me that much trouble. But recently, for some reason unknown to me, some of the function keys are not working like they are supposed to. the F1 through F7 and F9 keys are not doing what they should. The F8 and F10 - F12 do work, so i know that the Fn key itself is not broken, and the other keys do work for their alt key combinations, so they are not broken either. i am not sure at this point what the problem is. Can anyone help me out there?
