I have owned or used several iPhones and a few iPads but I have never had a MacBook. I was able to get a MacBook Pro from a friend for $100 was told that it worked. He didn’t have a power cord to it and battery was dead so I didn’t get to check it out until I got the mag plug charger for it turn it on and at first I didn’t get anything from it but after some research I finally got it to come on as described . But I’m still not getting anything on my display. I hit power and it seems to be coming on since the sleep lite comes on stays solid help me please
