Guys- a friend of mine is continuing to have a lot of problems with Snow Leopard. His battery isn't charging again on his MBP even after resetting the SMC, along with other glitches. Is it just a reinstall issue? If we can't figure it out, he wants to go back to Leopard. He's very frustrated. And if he does want to go back to Leopard, is there a simple way to do that without a clean install?
