I just recently upgraded from Vista Business to 7 Professional and in the process lost most of the Lenovo drivers. I have managed to redownload most of them again but cannot seem to get the volume (or brightness) display to work again. As a matter of fact, the volume buttons do work (albeit without the display onscreen) but the brightness does not seem to even work at all. I've searched around and found a general consensus that says to download the hotkeys drivers, but I have done so twice and it has not helped. If anybody would happen to know the correct drivers or a way to fix this issue, I'd very much appreciate it. Thanks!
