    I just bought a new Macbook Pro, but I think something wrong is happening. It`s my first notebook and also my first mac.

    When I turn off the lights of my room, the screen brightness goes down, and the keyboard backlight also goes down. Isn`t it supposed to be the other way around? If I turn down the lights, the screen brightness goes up, and the keyboard backlight also goes up?

    What is the `normal` situation?

    thank you :)

    No, it dims so that it doesn't blind you when all the lights are out, so you don't disturb others, and have to worry about changing the brightness if the lights go on an off in a classroom for example. Also it it's bright outside it brightens the screen so you can see it better.

    No. I don't think so. The screen brightness goes down so you would not get blinded by the screen. Same with the keyboard.

    It finds what the light is and then adjusts all of its components to optimize for that lighting condition.

    Everything seems to be working fin.
