"Pin 8 shorted to GND"
Did you mean pin 5?

SMC_RESET_L should be good now, if you get Magsafe amber light.
Are you using original Magsafe 2 charger?

Green light only comes back when battery is fully charged.

Yes, I meant Pin 5, was a mistype. Light is amber, but even without battery, normal behavior should be green light fir a couple of seconds then amber. Mine gets only amber and SMC_RESET_L is still under 1V. Yes, genuine MagSafe 2 85W charger.

Well, I gave U5110 area some heat and now the board started giving SMC_RESET_L signal 3.4V. Now the board is entering S3 state. I have all power rails in sequence up to PP1V05_SUS.
