    Okay, i should download the driver. I went looking wat driver it needed and it said i had to download Intel Graphics gma 3150 or something like that. I went dowloading it but it was only available For win7 (64 / 32x). I run win8 (86x). I Tried the win7 version but it said i had the wrong system requierments.

    I also discovered that it wint dim or Brighten the display when its charging.

    On a tablet, the display will most likely dim when on battery and stay lit if on AC when charging.

    I just ordered an Asus laptop for a friend of mine, it has Adaptive Brightness on it, it does not seem intrusive. I don't know if it is running though- I turned it ON in the advanced power settings, but it shut itself off, so maybe it is not part of the system or is not running for some reason.

    Sebas,

    Just to clarify:

    Did you use the Intel Driver Update Utility that I previously posted to see what drivers it says to install?

    In addition, when you turned off "adaptive brightness" and "dim the display", did you do so for both "On battery" and "Plugged in"?

    Yes, i did all that..

    And i get why it wont change when its on AC. When its getting charged a small light shines next to the sensor. And when the sensor spots light the screen brightens op to 100%
