  • 820-3476 - No Power

    I have a 820-3476 with no power but orange light on magsafe. Tracked it down to a short PPBUS_G3H under Q7630. When I removed the component, the short is still present and there seems to be soon peeling of the upper layers on the board. See attached picture. Is it salvageable ?

    You can try and dig it out and rewire it. But also check the resistance to GND on L7630. The 12.56V probably got to the 1.05V bus.
