Here’s the details… no hidden occurrences, I purchased a 2015 MacBook 12" Retina for a trip to Asia. I was traveling extensively via Plane, Train and Boat so I wanted something compact. It arrived used from eBay, but working perfectly. I was in and around China for 1 month and had absolutely zero issues with the unit. I arrived back in the states and still, zero issues. I was leaving for NY for a few days and placed the MacBook on my kitchen table, plugged in to charge. After arriving home I unplugged the unit and attempted to turn it on and nothing. No bleeps, bings or flashes… absolutely nothing. I believed it may have been improperly plugged in so I left it to charge again… nothing. Changed charger and cord… nothing. Something was obviously wrong and all Apple Support Documents say remove the battery. So, I opened the unit and displaced the battery from the logic board. No luck. I replaced the KeyBoard Ribbon Cable, USB-C Port and even a new Battery… nothing. So my question is, what happened? How does a unit go bad just sitting on a kitchen table? Before any rants - I live alone, so no my kids didn’t spill anything on it nor did anyone touch it while I was away. I tried all the SMC and PRAM reset methods too. Nothing works. Please Help.
This has happened to me as well. What you can do is replace the DC in power adapter (this is an internal circuit board) and you can order it from eBay for about 10 bucks.
same happened to mine, just got a used logic board and it works again, apparently these laptops have a reputation with bad logic boards. I lost all my data in the process. good luck!
