My aus f80 q the keyborad fn key not working with win 7

Did you try pressing Fn +Fn keys?

Make sure you Press and Hold the FN key then hit the key that increases or decreases the volume. If the FN key is not held down while you press the volume keys, they will do nothing. The brightness works the same way, you must Press and Hold the FN key then hit the key that controls the brightness.

if you look that the keyborad on the F keys there would be a key with a symbol of a computer and square box..press fn and at the same time press that key the described key

the symbols on the keyborad of laptop usually work with either the "shift" key or the function key abbreviated as 'Fn' . this key is usually located in either corners of the keyboard of the most laptops.

Good idea, Windows 7 is NO good if your equipment is less than a few months old... Pre 2008 stuff just isn't compatible. IMHO Win 7 is OK for brand new stuff, Otherwise I stick to XP... see everything works with XP..or nearly so.

ok

This works on the F30, F60, and F80.
