I'm running Windows 7, the keyboard works fine as long as I'm using it but when I leave the PC for hours and try to work after that, the keboard doesn't work and I have to use the on-screen keyboard to login and continue working on the on-screen keyboard only. The only way for the keyboard to work again is if I restart the PC.
Is there an option that I have to check or something? Anyone knows how to resolve this problem .. Thanks
