hi there. so it was a sudden problem. i used to charge my macbook 12’ retina 2015 with not the original charger one., sometimes with the original one. one day, my macbook won’t charge. i used the original one, no cable detected at all, cannot connect to my ipad/iphone. but when i used the -not-original cable one, sometimes it’s charging, sometimes it connects but not charging. sometimes it’s charging when i tried many times. it’s like the usb-c port kinda loose. already try SMC and nvram reset. no change. now i’m about to fix it with replacement, but i don’t know what is broken. is it the usb-c port, or the usb-c flex cable? i don’t want to go to apple authorize service because i’m afraid they will just tell me to replace both of them. please help me . thank you!
If they’re anything like the iOS devices, if you used a cheap aftermarket charger, odds are you damaged a USB validator chip inside the machine, and most likely would cause damage to the board, not the USB C port or ribbon cable. I would have it checked out by Louis Rossman of Rossman Repair group. He owns and runs his repair shop in NYC and accepts mail in repairs. Check him out on YouTube he’s very reputable and skilled in MacBook repair.
