Sony Vaio FN keys

Hello... I'm having trouble with my Sony Vaio VGN-FW520F with the Function Key not working i tried looking up the drives from the Sony US website and cant seem to find it. I had updated my Windows 7 Home Premium to Windows Pro and cleared my hard drive in the process. :confused:Thank you for the help in advance

Hello, welcome to :)

Perhaps you just didn't dig far enough into the Sony site ;) Here's a link to drivers for your specific model. So long as they're the right architecture (32 or 64 bit), the version of Windows 7 will not matter.
Sony eSupport - VGN-FW520F/H - Software Updates & Driversope this helps.

Thank you... i've been there i just don't know which one i have to download do you know the name if it? 64bit

Open start and type "System" and open that result. It will tell you some basic information including whether your PC is 32 or 64 bit.
