I recently did an upper disassembly on my MacBook 2015 and was doing the steps for a low voltage power up but when I plugged the power in the MacBook made the startup noise for a second then restart and did it again in these short cycles. I’m wondering if I improperly did the start-up process or perhaps something else is going on?

Hi John, I have the same problem, have you found a solution ?

What sort of logic board damage might happen if this step is not followed? One of our customers brought us his 2015 MacBook after attempting to replace the battery himself. The new battery is not recognized, and the computer shuts off after about a minute even when plugged in. Could this be the result of him not applying the low voltage power?

Did a batter replacement and woops… used a 10W supply for 15 minutes.

Then noticed my mistake and changed to 5W supply, but computer does not start at all.

Could this be the “logic board damage” mentioned?

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?
