First, TRUST ME, I googled this. Brightness / volume arent working. I have reinstalled the boot camp drivers and changed the setting in preferences to "use as standard keys" or whatever. Then when I press Fn, the keys just dont do anything... The keys have worked before and it seems pretty much random. Generally I have an external keyboard plugged in. Could that have something to do with it? Any help would be appreciated. Ill even take a google link to something I didnt see. I just want help. Thanks.
