Ppbus_g3h : 8.59V
PP3V42_h3h: 3.415V
PPVRTC_G3H: 3.328V
PP5V_S5: 4.987V
PP3V3_S5: 3.328V
PP5V_S4RS3: 0V
PP3V3_S4: 0.027V
PP3V3_SUS: 3.328V
PP3V3_S3: 0V
Passed in the UC, still the same.
After reheat the SMC in case of crap under it, now I have 2 quarter fan spin but still no Green/Orange light
And of couse all the rails are pulsing twice.
So I've also checked U6100, J6100, U1900, and U1950
SYS_ONEWIRE: 3.394V
SMC_BC_ACOK: 3.381V
SMC_ADAPTER_EN: 0V not shorted to Gnd as in diode mode I hace 0.550V
Sometimes if I reheat the SMC, the board starts ( fan spin full speed ), ALL_SYS_PWRGD slowly rises to around 1.3V ( when the board is still hot , looks like a bad capacitor somewhere) but still SMC_ADAPTER_EN: 0V
After the board cools down, I'm back to the quarter fan spin.
I'am able to read and dump the EFI with the Medusa, and according to what the Medusa displays everything looks fine and the Rom looks not to be corrupted.
Should I take the risk to remove clean and put back the SMC or maybe there's something else I can check before ( Crap under CPU?)
