Display screen black (no Apple logo/chime) after installing new batter
I just replaced a new battery on my MacBook Retina (12 in early 2015) after following the steps exactly as how they are listed on this article (even bought their kit).
I triple checked all the connections and they are well connected and I don’t see any damage (not that I think I did because I was very careful).
I also bought the recommended low voltage USB-A to USB-C cable. When I plug the cable in, the display screen is still off (black) no chime sound or the battery charging symbol. It’s like the computer is completely dead. Doesn’t power on when I press the power button. Nothing. Could it be a faulty battery (bought it from ifixit).
