    I just noticed the ambient sensor on my MBA seems to work backwards.

    When it detects light, the keys light up.

    But in pitch black, the key lights turn off.

    Anyone else have this issue?

    Yeah, this is pretty common if you check Apple's support site (and I think around here). Mine does the same thing. It's pretty annoying considered I paid so much but I've learned to live with it. It'll get fixed eventually. In the meantime, I just manually adjust it to make it come on. (That's fun to try and do in a completely dark room :) )

    i think it's a problem in the script they used. it's similar to the screen dimming one.

    I have the same "problem" with the keyboard backlight, but just wanted to clarify, the screen is supposed to dim in low light conditions - opposite of the keyboard backlight.

    It's shocking how many ppl on the apple forums don't seem to realize F5/F6 will solve the problem until apple posts a fix (which they claim to be working on).

    You know what? It's 2009 and Apple didn't fix this issue on their notebooks line! I have MacBookPro5,1 unibody 2.53Ghz revision A, and it's still have this backwards ambient light sensor issue and they have no solution. I have try to run Snow Leo GM and now back to 10.5.8 because they didn't solve the problem and looks like it's not a software problem.

    If everyone has the same "problem", maybe it is because the keyboard was DESIGNED this way?
    The macbook is designed for the optimal user comfort, and I believe the ambient light sensor was coded to adapt to the ambient condition. The keyboard backlight, like the screen brightness, dims in a very-low-light environment, because it is the most comfortable to the eyes. In only moderately low-light condition, keyboard/screen brightness is turned up because the illumination will not be hard on the eyes (user's perception).
    Very-Low light: Keyboard and Screen are dimmed
    Moderately low light: keyboard is illuminated but turned up
    Ample light: Keyboard illumination is turned off
    However I'd be suspicious if your keyboard backlight turns completely off in pitch blackness.

    BTW your iphone has the exact same behavior. You'll understand why if you try typing a text message in a movie theater with the auto-brightness disabled.

    Maybe I am one of the few lucky ones....

    but on my MBA Rev.B if I cover with my hand the top screen light sensor the screen will dim and the keyboard will light up.....this is how it is supposed to be working isn't it ? :) :apple:

    Mine isn't backwards?

    When it gets dark, the screen darkens and the keyboard lights up to a 1/4 level. When ambient light increases, the keyboard light also increases along with the screen until a certain amount where the keyboard light shuts off and screen goes to 3/4 - full brightness.

    I hate it when people do this:

    So you are the type of person who text messages while in a movie theater? I hate it when people near me take out their phones and start texting. The screens are so bright, you might as well ring in a flashlight to annoy the s**t out of me. I am really just making a point and I am not bashing you. But to all of you other f**ks out there who texts while in a dark movie theater, I would rather you talk quietly into your phone then to light up your my section of the theater...

    I was just going to say that you don't want to admit to this here.

    cover the light sensor and turn the kb brightness all the way up. that will fix it. don't mess with it after that
