My daughter recently purchased a MacBook through her high school and for the first few weeks it has been working fine. Suddenly, the screen is dim and barely legible. I have tried changing the energy saver settings, but it doesn't seem to help. I have googled around a bit and found a lot of stuff on a MacBook dim screen issue, but it mainly seems to be speculation and a lot of chatter on various lists about everything from Mac's attacking old ladies on the street to how cute someone's cat picture is. Does anyone have an informative link on this issue, or can tell me what the problem is? Cheers, Brian
