I was brought the computer as it showed no sign of life. Upon opening it I immediately noticed liquid damage in at least one critical spot.

I got rid of J6100 and cleaned/reflowed the other spots. C5126 was broken and as a result it's now missing from the board (should I replace it before investigating further?).
I didn't take a picture of the bottom as there was nothing to see in particular aside from mild corrosion on R5100, which I cleaned and I also made sure that it measures ~100kΩ.
As far as I can tell, everything appears to be in order except for SMC_MANUAL_RST_L being ~0.8V and SMC_RESET_L being ~3.0V. The power adapter is original and I'm sure that it works, but unfortunately I don't have another DC board to test.
However, if I understood the power-up sequence correctly, there is either a problem on U5000 or U5110 depending on which of the two signals is supposed to be pulled up first.
Thanks in advance.
