My 2012 MacBook Pro (non-retina) was charging for about an hour and I took it off the charger (I noticed the light on the charger wasn’t on either) and it’s not turning on, the lights on the side of the computer (to show the battery life) don’t turn on if I press the button, and my charger’s light isn’t turning on if I plug it in. I also can smell a faint burning smell if I stick my nose near the hinge / vent in the back. Any advice? I’m thinking it’s a failed / shorted out logic board.
