Hi all,
i bought another donor board off eBay to have a look at last week. 3437 which has no PP3V42 or PPbus shorts. In fact PP3V42 is present but I’m not getting a green light on the charger. There is sever corrosion on C3740, R3741 and R3742. U3740 looks ok though but I’ll probably replace it to be safe. Issue is both pads for C3740 and r3742 and one pad for r3741 are completely gone and R3742 is now reading ground on both ends.
I saw a slight amount of corrosion on pin 8 of U7100 but upon removal it seems fine so I’m hoping that was just surface junk.
Question is can the board boot without the above 3 mentioned pads intact? I’m not fussed about internal ssd I can always use a USB dock but I’m not sure if those are going to be required for boot or not. Unfortunately I do not have any donor boards to substitute these parts so it’s back to the Ali express waiting game.
thanks!
