Check with o-scope for pulses at SCL/SDA lines.
You can start replacing U7100 first; be sure R7100 is good.
The last option is SMC...

Found pulses at SCL/SDA lines. R7100 is good.Replacing U7100 . Rflow SMC but no luck. This is my second one mb but no luck. Dont know what the exactly issue.

Is this liquid spill?
Be sure battery connector is clean.
