Hi! Have done quite a few A1466 so far but this one is being a pain
Got an 820-00165 off ebay, board looks good, no repair attempts, minor corrosion around SMC and U1900, which I cleaned up
Didn't have S4/S5_SLP_L due to missing S5_PWRGD/DSW_PWRGD, reballed SMC, now I have PWRGD signals
When I connect charger or press the power button, I can see the current draw on my PSU going to around 0.5A and then back to 0.02A (sometimes does this a few times)
The fan does not spin when it does this, unless I try booting in SMC bypass, then the fan spins with the pulses but still no boot.
I can see S4/S5_SLP_L pulsing to 3.3V when pressing the power button.
Any suggestions?
