I just bought a used MacBook a couple days ago off of Craigslist. The guy told me about the computer and we both went through it and he told me all the info about it he could. I'm pretty sure it's 2006. Up until today, I used it for about an hour, and shut it down. I came back a few hours later, tried to power it on and nothing. The computer won't turn on, no sound, nothing. I unplugged the charger and took the battery out for an hour, put it back in and still nothing. I even tried to reset it but it still doesn't work. The battery lights all light up and the adapter charger stays green. I already tried to contact him but there's no answer. Could anyone help me out please? Thank you.
