I accidentaly managed to break off the DC (I think it's DC, the part inside the laptop that the power cord plugs into) connector. I can't for the life of me figure out how to open up my laptop entirely. I have unscrewed every screw but can´t find the way and I´m afraid to break it off.... it still seems to be screwed together in the middle. Any pictures or guides on how to do this,. thanks in advance
