820-00840-A not turn on

[andrespi]

I already changed u7000 and the problem persists

If all related resistors are good, then probably bad SMC.

 

[andrespi]

which resistors?

 

[2informaticos]

Resistors around U7000.

Also check voltage and signals for U5000 (SYM 2 OF 2), at page 39.

Where can I get smc, it has to be from another board the same, don't they sell it by itself? any story? I tested this board with a damaged battery and from there it did not turn on again.

Must get SMC from donor board.
New SMC doesn't have the proper frimware loaded...
