hello, today I decided to plug my iphone on my mbp 15 2017 while a usb 2.5mm drive was connected + power cable. For a strange reason my mbp stopped charging. When I restarted the computer and did the smc reset, all 4 ports simply stopped working. I had no way to recharge it by any port. Is it a common problem on these computer or anyone else had a similar issue. The computer battery is now fully dead. I’m heading to the genius bar tomorrow. It was already due for another repair.
