[QUOTE="pigoo3, post: 1558869, member: 56379"] Yupp...this does happen from time to time (rare). Unfortunately I don't think (or I'm not aware of) a method to determine a good power adapter & a bad one from an "At Home" DIY perspective (one that's about to do what your previous one did). All I can say is monitor it carefully. For example...my 2011 13" MBP's battery is fully charged (100%)...and the power adapter is "comfortably warm". Comfortably warm to cool hands on a Winter's evening at home. How warm is this in °F...I'm not sure. 100°F...110°F...??? And still...what is "normal"...who knows. I haven't seen anything published. I would certainly expect its temp to increase if my battery needed charging (but again what is a normal temp during charging)? And will the charger get hotter...the longer it needs to charge a more discharged battery (20% vs. 40% vs. 60%+ discharged battery)? This really isn't a well documented area. I guess this is just one of those areas we need to trust Apple (assuming this is a genuine Apple power adapter).:) - Nick [/QUOTE]
