I have a VIAO VPCF111FX laptop. Just three combination of Fn work properly like Fn+F4 (volume up) works, and the others have no effect. What should I do? Is there any driver for that?
Beside that ASSIST, S1 and VAIO buttons do not send any signal too. (I tested it with AutoScriptWriter app)
Factory install of Windows dose not have thus issue, but I installed an orginal win7.
