came in fresh, no liquid damage very clean. no fan spin

ppbus - 8.6v
pp5v0_s5 - 5v
pp3v3_s5 - 5v
pp3v3_sus - 3.3v
pp5v_s4rs3 - missing
pm_slp_s4_l - missing
pm_batlow_l -3.3v
PCH_DSWVRMEN - 3.23v
PM_DSW_PWRGD - 1.036v <--- is this the problem line?
SMC_ADAPTER_EN - 3.4v
PPVRTC_G3H - 3.3v
RTC_RESET_L - 3.3v
PCH_SRTCRST_L - 3.3v
PCH_INTVRMEN_L - 3.2v
PM_RSMRST_L - 3.2v

I Triggered SMC_ONOFF_L and checked for drop pulse at PM_PWRBTN_L. - goes from 3.4 to .3 back to 3.4v

Incorrect PM_DSW_PWRGD should be 3V.
SMC and PCH are both connected there.
May have accumulated crap underneath PCH, or even SMC.

If PM_SLP_S4_L doesn't pulse at same time with PM_PWRBTN_L, PCH is suspect.
But should get first correct PM_DSW_PWRGD.
Strange to get 3V3_SUS actually.
Just in case, check S5_PWRGD and SMC_S5_PWRGD_VIN.

You may need to reball SMC...

S5_PWRGD - 3.4v
SMC_S5_PWRGD_VIN - 3.4
I remeasured PM_DSW_PWRGD and now it says 3.4 (weird)
PM_SLP_S4_L pules when i triggered smc_onoff_l

do you think its smc?

My mistake, sorry.

If PM_SLP_S4_L pulses, then check for pulse at all big coils.
Also check PM_SLP_S3_L and ALL_SYS_PWRGD.
