This site is for anyone that doesn't want to spend money on quick and easy macbook fixes you can do yourself.
My problem was that my macbook battery was defective or something and it kept expanding and eventually expanded so much that the back cover popped off. I got a new battery and it was working fine for a couple weeks but now this one is getting really hot and the mac has started automatically shutting down when it gets really hot. So, to fix this I got one of those laptop coolers that has little fans under it. It helps out a lot, but I still can't use it for longer than 3 hours without it overheating.
