I recently installed Windows 8 Pro on my Sony Vaio notebook. I have just about everything I can think of configured to my liking, except for 1 thing that is really bothering me. My brightness function keys on my keyboard no longer work (Fn+F5 and Fn+F6). I can adjust the brightness from the settings section in the charms bar but not with my function keys. I have tried installing all possible drivers and have had no luck. Does anyone have any ideas or know of any programs I could possibly use to set the brightness keys?
Thanks in advance
edit: recently discovered but not as important my Fn+F7 that acts as windows+p also doesnt work. As well as Fn+F9 and Fn+F10 which acts as Ctrl+ "+" and Ctrl+ "-" do not work. and also a Fn+F12 that I'm not sure what originally did (looks like a can with an arrow going through it with two "z" 's to the side might have put something to sleep or something not sure.
also my 3 volume Fn commands work but those are the only ones
