OK I'm half way through, it's a ton of work. basically all of the lines are pulsing. both in and out volatges. they're not present but they are pulsing when connected. But two things which are strange.
1. PP1v05_S0 only has 200 ohms somestimes less to ground, in fact in continuity mode my multimeter beeps.
1. and this one is completely bizarre to me. U8050 and the line SMC_PWR_EN is 0V when power is going to the macbook. as soon as I disconnect it goes to 3V. WTF? it takes at least 30 seconds for the 3 volts to disappear even though there's no power going to the board
