Why no power after replacing Mag In-Board
Long Story Long! Spilled wine on computer; took it apart immediately, wiped it down, threw it into a bag of rice and waited a day. Hooray, it powered up using battery and worked fine. Waited too long, however, to test power adapter, which did not work (N.B. it was starting to go anyway). Took it to Apple and was told it was the Mag In-Board (gave me a new power cord because of strain). Apple refused to consider repair since they detected the liquid damage. Decided to replace in-board myself and ordered part and two screw drivers from ifixit. Read Guide and then some silly advice from two users to skip steps between 6 and 18. That didn't work so had to start from beginning. Finished and it lighted up (flashing green, with occasional amber) I was delighted. But . . . doesn't power on. If I remove battery connector from logic board light turns to amber so it is connecting. Read further and decided I reattached cable ribbon incorrectly and took Mac apart again--almost impossible job getting ribbon in slot and I may have damaged it (is it blue on underside as I seem to be missing a piece that's in picture?). Also, I can't reattach speakers, both, second time around. Probably broke the connectors. Did an SMS, nothing. Battery was completely drained when I started--could that be the problem? Anyway, if it doesn't work within two days, I'm selling it for parts. As an aside piece of advice. Please, don't listen to users who tell you not to follow guide! You must remove logic board to change the Mag in-board.
Is this a good question?
