After complements, I have Mac Book Retina 2014. The battery does not charge. The technician is trying to fix it. Says corrosion due to moisture seeping in from keyboard is the problem. Has even given an ultra sonic test. Now going in for more advanced diagnosis. Is it possible for these technicians to replace good parts with substandard ones and pull a fast one on me? Appreciate a reply.
