I have a Sony VAIO VGN-AR21S laptop that originally came installed with Windows XP Media Centre. I have rebuilt it with Vista Ultimate and installed all the drivers and utilities supplied on the VAIO support site:-
However my FN keys are still not working (e.g. adjusting brightness, changing display mode to use external monitor etc). Please can you help?
I was under the impression the VAIO event service was responsible for these buttons, but the service is installed and running.
