I'm going to try and get apple to send me a new MBP. I installed a gig of ram on it yesterday, and I noticed the bottom of the battery is becoming brown/blackish. I'm having these same type of colors appearing on the corners of my MBP casing, too. I'm gonna tell them to send me a new one because it is a fire hazard, or I will send it to them, and I will tell them I want my money back. <---Works like a charm almost everytime for me. Do you guys think they'll send me a new one.
