Hi, I have asked this question before, but nobody can give me any further assistant. Please note that I have already installed the hot key feathers manually, also, someone told me that I need to use the lenovo's graphic card driver, but I am not sure where I can get it, does any one can give me a link for it? The original message is as follows:
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. Thanks

Remove the video driver (Controlpanel - Programs and functions) and install this one:
Update install from Vista to Win 7 can lead to driver problems and slow growing system inconsistency. So it's always the best method, to do a fresh, clean install after back-up the data and the folder C:\SWTOOLS .
C:\SWTOOLS contains a few setup files, which only are availiable on factory default installation.
