I have sony vaio VGN FS415E.
The Fn key (to control volume/brightness etc) does not work (although it activates scroll lock fine).
I have installed all drivers and utilities from Sony.
I have checked that hkcmd.exe is running in processes in task manager and that Vaio Event Services is running as a service.
Yet the Fn keys still do not work.
Can anyone help?
i am awarding 250 points for this as i cannot find anything that works from googling.
