So I have o nthe bench an 820-00165 that the customer said he took to another shop and they said there is a problem with the power distribution on the LB. I was like what?! never heard that before. I checked it out and asked for history and he said his daughter was using it and it just stopped working. I powerd it on and the BL is not working but is will boot to Apple logo but gets stuck on an empty progress bar. I took the board out and U7701 definitely suffered liquid damage as well as the resistors to the right of it. U3210 has a tiny bit of dried stuff above it. My question is, neither one of these could cause the LB not to load the OS correct? I looked the whole board under MS and do not see liquid on the PCH side or by U6100.

Liquid spill can affect BIOS sometime.
Try known good working BIOS as first step; clean ME, of course.
