    I recently installed Win 7 64-bit Professional on my NP8662 (had to do a clean install from Win XP) and the brightness buttons refuse to work except during start-up, during the POST and such.The Win 7 sliders don't work either, but the brightness IS reduced when my battery gets low.

    I'm perplexed as to what could be causing this... anybody else having this problem or any ideas on what could be causing this? Could it possibly have to do with my BIOS?

    Did you get the latest Win7 driver (called 09Hotkey) from Sager or Clevo site?

    What video driver are you using? Same thing happened to me so I had to revert back to 186.81 which is the best video driver for me so far.

    I could not change my screen's brightness when I installed modified desktop nvidia drivers from laptopvideo2go. Since then I've installed the latest notebook drivers from nvidia (195.62 WHQL) and it solved the problem.

    Yep, seems it was the drivers from laptopvideo2go that was causing this. I've reverted to older drivers and it seems to be working fine now. Thanks for that.

    Now I'm off to bench crysis and see if it runs as well... thanks a lot guys.

    Stick with WHQL from nVidia only. I've known laptopvideo2go drivers to break things more than help, unless you find a driver that really helps with one game you play, it's not worth it.
