I slipped a piece of paper between the camera module and the thing that's below it. The piece is folded over a few times to gain a thickness of about 1~2 mm The pressure expressed is enough to keep the camera/flash from shorting.
THe Memory cap for this system lies at 6Gb, but that 4Gb SO-DIMM is rather expensive. I already run Snow Leopard which took a full 2 degrees of the max back-then... but that's it. SMCfanControl is currently running automatically at startup, and helps keep the heat down once it's there, if there's no real cure for the issue, I will let it slide, so long as that G86 chip doesn't go bad on me, it's no real threat to my health.
Looks like a mild case of backlight bleeding.
Judging by the photo it doesn't strike me as product-threatening, but you might want a second opinion. and nothing's wrong with your English, it's perfectly understandable. :ADDED 08-12-09 I fear you're looking a ta works-as-designed issue, I've seen Dell notebooks, HP All-in-one's and branded monitors you name it... displaying similar issues(Though most in a larger degree). -IF it really is a defective product, an applestore should be able to have it replaced, no way that's a case of Customer Abuse.
-If it IS normal operation, no replacement part is going to resolve.
