I just replaced a new battery on my MacBook ProRetina Pro early 2015 and bought this cable and adapter after following all the steps and instructions but when I plug the cable in, the display screen is still off (black) no chime sound of battery charging symbol on the screen. I plugged everything back in correctly and followed the steps exactly how they said and my mac won’t display anything. What could be wrong?
