820-00138-A missing components

[javier_herart]

I bought this board on ebay and it arrived damaged (see attached image, damaged and donor board).

All resistors/caps close to j8300 were ripped, I cannot see the trace in all of the pads so not sure if I could install the components from a donor board.
The boardview wont match the board, could you give a hand to identify what are resistors missing?

(Its hard for me to return the board, that is why I am considering fixing it) .


Thanks!

You must solder C8328/9 for pins 10 & 11.
All C8350-8 caps are not critical, forget them.
You can make a short instead of R8300 (0 ohm).

The boardview is from 00163 and many other components correspond.
The big problem is to verify continuity for the pins 2-8 with the other points on the board; pin 3 with R7758/60, for example.
May have luck if you find them on the boardview.

The connection traces are inside the board.
If the points are underneath the ripped pads of the caps, will need to run wires; if you cannot reuse these points.

Thanks for your help.

I added 3 resistors and the board seems to be working, however the battery is not charging, no green/orange light, I do see the lightning on the battery icon. Any help?

You must get the amber light on Magsafe first.
SMC needs to communicate with 1-wire memory from the charger, in order to enable charging.

Inspect U7000/1 area and their traces.
Tried another DCIN board?

It seems DCIN board was not completly connected...

thanks!
