No short on system side ,replace u7000 with 3 different one and still gives only 12.25V ,macbook have green light on charger doesnt turn on ,everything look clean ,R7021 and R7022 measure 10K

I'd hope you mean 10 ohms not kilohms on those two resistors...12.2 means SMC not running. Diode mode pin 2 of R5280 and R5281 to see if either or both lines are being pulled down. I think this is the one with the completely edge bonded SMC, so my best guess is your SMC is dead.

replace the smc now ppbus_g3h is 12.52v but missing pm_slp_s4

Hmmm. Any history on this liquid drop damage tech damage etc?

SOLVED I just reflow SMC little bit more and now working ok
