I have a Sony Vaio VGN-CS36GJ i just install it with window 7, with the VAIO Windows 7 Upgrade Campaign,i was given the home premium 64 bit upgrade kit, after installing the fn + F5 and F6 worked displaying this picture i attached. but i can't change the brightness, it only goes up and down by one bar, is this the driver issue? no conflicts are found in the device manager. can this be fixed?

and install it. I have a vgn-cs36gj (VGN-CS36GJ_Q) too, and it worked for me :)

Thanks for taking the time to reply to this problem i fixed it.

Hapoogold gave me the driver download site, all i need to do is just download the driver. and install it. I guess this only applies to the sony models that is applying for the Window 7 upgrade Campaign. if you try to install the driver and it says it's the latest driver. you can try to uninstall your driver and reinstall with the one you have downloaded. Hope this helps i am not really a computer person...

I used Event Managment for my AV Mode, by right it should auto detect because it's in the motherboard. but you can try to download from the site: VGN-CS36GJ : Downloads : Support : Sony Australia

maybe you might want to let windows update do abit of updating first? then see what happen next? or you can send it to sony's servicing center, it's faster that way, ( by the way my laptop model cannot be found also.... how weird.... )
