I have the June 2012 MacBook Pro 2.9Ghz i7, 13". The last one that has upgradeable internal components. Anyways, it got a bit of water on/in it, but continued to work fine for a bit. Then the charger light on the magsafe connecter became a very dim green, and the computer wouldn't come on anymore. I took the bottom off and there was some water on the battery, which I dried off. I left it open overnight to dry out, but no luck this morning. Is there any way to save it?
