[QUOTE="tycksena, post: 1623179, member: 338390"] I am trying to repair a late 2011 Unibody MacBook Pro that my wife spilled soda on. I have it all apart and plugged the charger into the magsafe bd and I am getting a very faint green light most of the time (sometimes no light). This is with the magsafe bd unplugged from the logic board. When I plug it into the logic bd it acts the same. I have tried cleaning all that I could with isopropyl alcohol and a toothbrush and don't see any signs of corrosion. I'm not getting any power or anything though. I have tried powering on using the power pads too with the keyboard disconnected and still nothing. What would the next step be in diagnosing? What voltage should I be getting out of the magsafe board? What voltage at the power pads? And does anyone have a schematic for the model A1278 Logic Board? [/QUOTE]
