820-2936 no green light

[Yoel Ren]

pp3v42 present, but no smc_bc_acok
i have 3.9v at u7000 acin
resistance between pin 17/18 is normal at 3 ohm
but resistance between 27/28 is too high, the trace from pin 27 of isl to pin 2 of r7022 is good
the trace from pin 28 to pin 2 of r7021 is good, but i probe between 27/28, the resistance is too high, can someone give me some pointer thanks..

Did you check traces from R7020 to R7021/22?

thanks, there's missing traces from the back of board from r7020 to its via nearby..
after i get green light, i still dont have pp5v_s5, replaced u7200 and got pp5v_s5..
after that i replaced 2 resistor for pch_intvrmen and pch_dswvrmen and i its turned on now..thanks a lot,,
