If my MBP is shut down and its charging, and when it finishes charging, the computer turns on. Also, when i connect the mag safe power adapter to the computer, it turns on with out poshing the power button. And if the computer is running of the battery for a few hours, at around 40% it shuts off. but the ginius bar gave me a new battery but ONLY that problem was fixed. when i went to the ginius bar for the other problems, they ran some hardware tests, and it passed. now they had me reinstall Mac OS X 10.4 Tiger. The Problem continues. any idea of what might be going on?
