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. Thank you for the help in advance
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.
