Hello to all, I have been scouring the internet looking for answers to this. Maybe someone else out there can help. I have 13 VGN-BX760 laptops. I have started upgrading them from XP to Win 7 x64. Evrything works fine except for the Shift keys! Neither of them work at all. (actually, the first one worked fine for about 3 months) I have tried new keyboards, nope. I have tried all of the filters and sticky keys tricks, nope. I have called Sony and they say there is no known issue. I find that hard to beleive since it has already happened to 2 of them. Shift keys work perfectly on an external keyboard, so I know it's not the OS. Ideas?
