  • [SOLVED]820-3662-A orange light no boot?

    Hey all,

    i got this MBP 15".

    History: had some milk spill. fortunately didnt go through keyboard. All WDI are intact and looks like it hasnt made any contact with the board except around battery connector.

    SO FAR: under inspection of microscope everything looks super clean except one cap next to battery which I replace from a different board. still no power. despite being so clean i still ran through the ultrasonic.

    Any suggestions?

              So is there a green and then orange light present now? PPBUS at 12.6V means SMC is running so make sure the magsafe board is good if there is no orange light.
