Re: 820-00928-a Schematic needed

This schematic is for 820-00281 that was wrongly renamed 820-00928.brd because there are differences.

Same problem about this cap here https://www.badcaps.net/forum/showthread.php?p=1022772

Find solution about this cap! Boardview 820-01814 that look alike shows that this cap (with the other two on the other side of mobo c0402 c0403) have both legs GND (i don't know why).

1) Remove the cap and confirm that the short is fixed.

2) Check the cap while it is off the logic board to see if it is shorted or not.

3) Check the resistance to ground of each PCB pad where this cap was soldered. Once side will probably be ~0 ohms = ground; the other side of the PCB pad should not be 0 ohms.

You can use your meter to locate where each side of this capacitor is connected on the PCB and update this thread.

Maybe the Layout and Diagrams are useful :bersuka cita:

Thanks for the files but 820-00928-A is different than the boardview posted here.
You can check here https://logi.wiki/index.php/MacBook_..._composite.jpg
in the upper right corner, there is an extra capacitor next to c4912.

The specific extra capacitor is shorted on mine.

I do confirm this schematic is not matching A1707 820-00928-A board.

Already found few "missing" components. 🤣 Most obvious one is U5700 which clearly is not soldered on my 00928-A board.
