I just received my MacBook Pro from my brother a few days ago. He has an Apple store on eBay, where he builds and sells Apple products. It was just a couple hours ago using my Mac, I had my phone charging from one of the USB ports and it did say USB ports are being disabled from a little warning screen on top right. Then next thing I know my computer just shut down. Now it won’t turn on at all. Won’t power on! My charger has a green light and charges my daughters Mac. I just can’t think of anything else that may have caused this. Is it the power supply? I’m dreading having to call him, then pay to send it to Nevada, then may have to pay for it to be repaired.
I think its safe to say you didn’t do anything to cause this. Clearly the system has a deeper problem with its power system.
