      You can see the component IDs match, just the placement is different, and how the pads on the IC PU8700 TPS51486 "look" a bit different.., but the pin numbers match
      Some components even go to the other side of the board, also there are some "hidden" jumper traces

      EDIT: Yet the boardview i got from that thread doesn't even match exactly your board, but at least the schematics should help for that section
      EDIT2: Measure resistance to GND on pin 98 of the EC (HWPG), there's a convenient cap nearby (CI16) where you can check
