820-2523 super strange problem

No idea what you mean. I asked if the signal toggles when you press the power button.

and im not sure exactly what you mean, i dont have a scope, all i can tell you is something happens on that line when the smc_onoff_L pads are shorted, so im giving you the resistance to ground and diode mode to ground on the test point

 

[dukefawks]

You should not measure resistance or diode with power applied. You should clearly be able to see the voltage drop and come back when you press power button.

 

[peterfixit]

i did see that

Just out of interest... Did you happen to buy your "genuine" charger from Amazon or eBay? I bought 4 chargers from these fuckers 2 of which died and 1 would not power a board without battery. At least one of them works. They all have a lovely Apple logo on them and all say 85W and look the part but they don't do what they should.

Get a charged battery and see if it charges and powers on from that.
