HI, I know this topic has been listed before. But I just got that problem recently and sick of it. My powerbook 12", got a brighter right hand buttom area than the rest. The left hand top corner is the darkest. I read old posts of this uneven brightness or uneven illuminations on 15" pb. So far, I have seen some ibook in my company got the same problem. My question is: is fixing uneven brightness is a mission impossible? or apple is just a cheap hardware supplier? I just bought this laptop 4 months ago. Still 2 yeas to go I think.
