Answer to: Won't Charge: is it battery, I/O board, or battery connection?I would like to thank LenaFox and Dan for their responses, I apologize for not noticing them. In response to Dan's enquiry about coconutBattery results, the app shows NaN in many fields and 0 or 'none' in most others, it was really quite disconcerting. I would post a screenshot, but after replacing the battery the macbook works like its brand new! As occum's razor would suggest, it really just was underclocking the CPU since it was registering a faulty battery. Hopefully these symptoms and result help someone in the future, if my $50 Aliexpress battery explodes in my lap I shall post a warning on here, but so far so good! Keep on keepin' on, iFitit community!
