My MacBook Pro 2012 13 in just randomly shut down while I was watching something on Youtube. The screen has turned black and I cannot turn it back on. My charger was plugged in while I was watching the video on my Macbook,and now it has flashing orange and green. This has happened before and I had to go to the apple store to fix it, but I want to do it now since I have a project for school to do and since I want to keep the video I watched private to the genius who looks over my computer (It's nothing bad). But last time I had this fixed, the page on safari that was used before my computer shut off popped up and it had felt uncomfortable. Anyways, is there a way to fix this by myself?
