hi. battery of my macbook pro exploded (previous generation, http://store.apple.com/us/product/MB133LL/A). http://www.dolphinstreet.com/images/macbook-pro-battery-exploded.jpg should i take it to mac or would it be ok if i buy a new battery online? *i also have a new generation pro. and i wonder, since new gens are single piece, what will happen when this one's battery explodes too ?
