I have the same problem here with an E420. I think I've got the latest bios update (from 22 nov) and the latest video driver, but when I switch to my dedicated video card, I cannot change brightness. Otherwise, it works fine with intel hd. Have any other updates come up yet?
It's rather paradoxical if you compare these driver problems with linux from the end user's perspective. I really had more headaches trying to solve all sorts of driver problem with switchable graphics, screen brightness, touchpad and so on than in KDE4, which is much less attentively done than windows 7.

I'm not sure what should I do regarding what JameZ said. On our notebooks brightness control doesn't work at all by F7 anf F8 keys. What's the Hotkey exactly ??

Am referring to this one.
Installed, but unfortunately still doesn't work on dedicated graphics...

F7 and F8 function are NOT correct, pressing this keys cause display graphically on the screen, but nothing else happend.
Brightness does not changed.
