Help with troubleshooting the right power issues A2338 motherboard

Hey everyone!

I'm trying to fix a laptop (Apple m1 A2338 macbook air) for a friend, and I'm trying to identify what on the motherboard is broken (she spilled a little water on it).
The laptop does not power on.  I have the motherboard out, and I have a volt meter and soldering tools. I found a few youtube videos on it, but there is no visible damager at all on the motherboard. Most of the youtube videos I have seen show someone identifying visible damage and the resoldering a few things.
I have no visible damager anywhere on any side of the motherboard. I have a hunch that one power chip is just not working and the rest of it is good. But I'm not sure how to identify it.

I guess what I'm looking for is some help for identifying where on the motherboard I can check with my volt meter so I can identify the issue. The motherboard look so clean, I feel like its got to be something simple!

Thanks
Phillip
