This machine came from a different shop.
Damage to UA600 and nearby PP5V_G3S support. Replaced chip, resistors, cleaned traces, verified continuity and, found 5V present on PP5V_G3S and GPU_COREREG.

Damage near SSD0 components as ususal but no shorts. I lifted the controller to check even.

It powers on, gets 20V, starts charging the battery and after 20 seconds it restarts and tries again. I kinda don't know where to start, all the damage has been washed away :(
