My dad has a Toshiba Satellite running Windows 7 and while he was playing solitare he somehow locked up his keyboard. We have been trying for the past several hours to unlock it, obviously with no success. FN keys, device manager, turning off and back on, nothing. The device manager says its working properly. There is no icon in the tray, nothing telling us that it's off. PLEASE HELP! Any suggestions would be welcomed!
