    The wierdest thing is happening with my Ibook g4. While i am using it, the backlight or the screen(i'm not sure which it is.) will slightly dim and then get brighter. As I type this it is getting brighter, now it's dimming. Any ideas what the heck is wrong with it? I'm really hoping it's just my eyes, not the laptop. :p

    It's probably the ambient light sensor adjusting screen brightness to the current light conditions.
