Hi everyone,

It's been a while since I've posted here, but knowing what a bright bunch you all are I was hoping for some help.
I know the majority of the community look at laptops and custom build PCs, but I'm appealing to the Apple experts in the forum.

I've got a 820-3115 that I purchased as faulty. The laptop obviously had a repair attempt previously and there are signs of widespread liquid damage.

I'm getting no PPBUS_G3H created on the board.
I have PP3V42 across the board.

My input voltage is around 16.5DCV

All signals for the OneWire circuit are present, and I get a green light for a few seconds which then turns off and comes back.

This is my first dive into Macbook repair, so I'm hoping someone more experience can bail me out of this one.

Thanks in advance!

Joe.
