    When I turn on "Illuminate Keyboard in Low Light Condition" the keyboard lights up when I turn off the room light...

    BUT... when I turn the lights back on... the keyboard illumination becomes even brighter!! 0_o

    Weird huh?

    Has anyone else encountered this? Anyone got a fix?! Thanks

    the ambient light sensor is located beside your isight camera, so, if your head covers the ambient light sensor light in your room, casting a shadow over the isight camera area, the keyboard will indeed illuminate.

    It should be the other way around. When you go into a bright room, the keyboard lights should shut off. have you tried a PRAM reset?

    This is normal.
    The keyboard lights will turn on when it's a bit dark but it will also auto adjust its brightness based on how dark the environment is.

    Try this in a well lit environment:
    Very slowly cover the ambient light sensor (beside the iSight camera) until the keys light up.
    Observe the brightness of the keyboard lights.
    Then TOTALLY cover the ambient light sensor. You will notice that the keyboard lights will dim.

    He mentioned that the keyboard becomes brighter as the conditions get BRIGHTER not the other way around guys. :)

    Yes. I understand what TS said and this is normal.
    There is a certain threshold before the kb lights up and the intensity of the kb lights vary on how dark the environment is. So, with the kb lights on, when the environment gets more dark, they auto dim and vice versa. This is so that your kb lights won't be too bright when the area is really dark.

    Do the test that I mentioned above and you will see.

    mine doesn't... it gets brighter the brighter the environment gets...

    Even if you shine a flashlight directly at the ambient light sensor?

    @natsgo: No it is not normal. He mentioned that if he went into a BRIGHTER room, naturally, the keyboard lights should switch off but then it is the other way around for him. Bright room=brighter illumination on the keyboard.

    Yes he could have gone to a brighter room but the question is - is the "brighter" room bright enough to trigger the kb lights to switch off? If he moved to a brighter room but the room is still not bright enough to cause the kb lights to switch off, the lights will become brighter.

    Check the video I made here - http://www.youtube.com/watch?v=_a-LnULFt8Y

    Note that when I put my hand on the ambient light sensor to simulate a dark room, the kb lights dimmed but when I removed my hand to simulate a "brighter" room, the kb lights became brighter.

    If the TS' kb lights still light up when he is in a very bright environment like outdoors at daytime or when he shines a flashlight directly on the ambient light sensor, then we can conclude that there's something really wrong, otherwise, that's just normal.
