I disconnected the battery from this working computer to remove an efi lock and upon reconnecting the battery I accidentally had the screw not aligned and it sparked at me, since then the computer will not turn on and I believe the spark from the battery killed it.
I get 0v on PP3V3_G3H
Ok I checked most of the coils on the backside of the board and they pulse.
on page 58 and 58 most things were pulsing on output
I went over the power rails again, a lot are pulsing, and PPDCIN_G3H was steady but I had an open line
ALL_SYS_PWRGD Pulses between .9v and 0v
Do you want the I/O Flex Cable connected when testing? I noticed without the cable connected PM_BATLOW_L is 3.3v so probably false alarm.
Making temporary contact to SMC_ONOFF_L gave these results
PM_PWRBTN_L drops to 0.357v
PM_RSMRST_L no change
PM_DSW_PWRGD no change
PCH_DSWVRMEN no change...

I have a 2013 820-3476-a that is in great condition with no sings of liquid that turns on but freezes within 10 seconds to 1 minute. I have tried minimum system configuration, different flash drives, different os's. It also freezes on an os install/setup screen and even before loading into the...
