Angel Nunez, I am not a Mac person, just a person that enjoys hardware of any kind. Now with that said, how well are you in testing circuits, SMD components and soldering very small components? The reason why I ask is because that is where this may just be going. The very first thing, besides all the things that mayer (a real Mac expert) already suggested, is to check the fuse F7000 (7Amp). It protects the power and battery circuit. After that check the Zener Diodes D6950, located just above your battery connector. If you post an image of your logic board, I can mark those components for you. This may just be strictly academics since this would be board level repair and is very tricky to accomplish.
