Take a good look at the logic board around where the battery connector is, it is possible that you have knock of a small component of the logic board when you have replaced the battery. You might need a magnifier or microscope to see it, at the place where component is missing you can make a jumper between the two pads. Sorry for my poor English but I hope you understand what I try to explaine.
