I just noticed that the bottom edge of my 15" PB screen is darker than the rest of the screen. Its from the bottom edge going about 5-6mm up from there. When I make the background completely white the discoloration shows as a slightly yellowish/brownish tint. Not very dark, but it is noticeable. If I touch the bottom of the screen, it feels much hotter than the top. I guess that logical considering the vent's all along the back of the machine. Anybody else have this problem? Could my screen be getting too hot?
 
My screen has a slight hue to the very bottom of it, doesn't seem to be heat-related, though, as my screen feels only slightly warm.
 
sleep your computer for 20 minutes to cool, turn it back on, see if it's still there, and get back to us. that way we'll know if its heat related or maybe the case is putting pressure on it.

I just let me mac sleep for approx 60 mins. Seems like the screen has cleared up a bit again now. Its not 100% though. So I'm not quite sure what's causing the problem :confused:

Did you have the computer running with your display shut? Perhaps this is causing it to overheat. I know on my peecee laptop my screen gets rather warm (no observable discoloration) when I leave it running with the display shut.
 
My buddy had a similar problem with his Toshiba notebook yesterday. It happened after he was running it for 3 hours or so, rendering audio tracks and then burning a dvd or two from DVD Studio Pro, and most of the time his fans were blasting away. Sounds like heat may possibly be a cause of this, although i am comparing two completely different types of computers.
 
My powerbook is just operating normally. Open and nothing heavy. Bit of internet browsing, email and iphoto. Nothing heavy. That's why I'm sort of surprised. Usually when it gets REALLY hot I have to take it off my lap cause it starts to hurt.

I'll keep an eye on the discoloration. It seems okay now. My powerbook has been running for about 1.5 hours on end now.

Hmm, that is really odd.
Darn, there goes my theory. ;)

Your computer wasn't experiencing a kernel panic that would have caused it to overburden the system (ie- cpu, hdd, etc...) was it?
 
no kernel panic or anything. I'm out of ideas too. It's still fine now.
My warranty is valid for another 6 months or so. Plenty of time to discover a problem! :p

Well, there goes my last idea as to your described problem. Sorry I could not have been of more help.

Guess that you should call up Apple to take advantage of your remaining AppleCare.
 
When my iBook G4, iBook G3 900, and iBook G3 500 (when I had it) 's screens heated up, they had/have a 4mm or so from the bottom of the screen dark line. On white it looks kinda brownish. Apple said it's normal.
