Hi, I have a T500, and ever since I upgraded my system from vista home basic to win7 64bit, the indicator for the volume and the brightness does no longer work. When I press the buttons on the keyboard, the hotkeys does work, but there is no display on the screen. I downloaded the on screen displace for my machine for this system, but still problem persist.I am wondering why this happens and how to solve this problem.
