    Hi Folks.
    I have installed the windows 7 version on my T400 with switchable graphic card, I also installed the drivers that Lenovo provide for windows 7 like the ATI graphic card, system interface and hotkey features drivers. However, I cannot control the brightness of the screen with the combination of keys that includes Fn. The green panel goes up and down when I use this combination of keys but brightness does not change. In fact, I cannot find a way to change the brightness of my screen
    Any suggestion regarding how I can solve this problem? Thank you very much for your feed-back.

    Did you update the bio to the latest version? Update that and see if that works. When I first installed Win 7, it was the case with mine as well but updating to the newest bios fixed the problem. But, there is still some bugs which lenovo needs to fix with the drivers and the brightness refuses to work with the ATi GPU enabled.
