The title says it all, the brightness for my Macbook Pro can't change, it's stuck at 1 tiny bar of brightness, which is about as bright as something being lit up by a single firefly in a cave. I've tried to press the increase brightness button, and the computer screen has the brightness bar thing showing that the brightness is increasing but nothing changes on the actual brightness of the screen itself. Anybody know what's wrong? I just think that some wire broke.


Also, I'm not entirely sure if it's okay to post this here.

Maybe the button has been moved off the sensor or its just a faulty keyboardOR for whatelse i thought you might be saying, Your backlight may have gone bad or blownIf its your backlight take it to a local help deskIf its your keyboard you should be able fix it from your display settings

Do you have a glossy screen?
