Hi all,

I have a 17" Macbook Pro purchased last year when they became available after the keynote in October. My question is has anyone out there experienced the problem where if one puts their hand or face close to the isight the monitor displays a substantive dimming effect? I am not sure when this problems started, but it is has been driving me crazy. I am assuming this is not the norm and is a potential problems?

Any help would be greatly appreciated!!

17" Macbook Pro, Mac OS X (10.5.8)

    The ambient light sensor is up that controls the backlight of the display if you have that preference enabled in System Preferences. In System Preferences, under Displays, is the box checked... "Automatically adjust brightness as ambient light changes."

    Just noticed the last few nights my screen going dim. It is plugged in to power, the option for ambient light is checked in System Preferences.

    If the room is the same lighting conditions why would the screen dim? In fact, if the room is getting darker wouldn't the screen tend to get brighter and not dim.

    I have had the machine a few months (June 2009), and only recently in the last 2 nights noticed the screen is dimming. My concern is that there is something wrong with the display, since I never noticed this behavior before.

    If I put my finger over the video cam the screen gets brighter.... guess the light sensor is right next to it.

    Your thoughts... do you think I have an issue?
