I have a Sony VAIO with Win 7 64-bit, purchased around 2 months ago. Everything was working fine until yesterday when Sony VAIO update popped up from the task tray and prompted me to update a bunch of things, which I did. The entire process was automated as it was one of those system updates. After the update, I restarted computer, and then all the function keys stopped working. E.g., pressing FN + F1-12 won't do anything. Before the update I was able to use FN + F3/4 to adjust volume, but now nothing happens. Does anyone know what's going on? None of the updates failed to install and I restarted computer just like it said, and I'm assuming all updates that need to be installed will pop up in either Windows Update or VAIO Update? My Win update says my computer is up to date as well. Thanks.
