This board had some light spill damage on the right side of the board (looking at it from the bottom) so it wasn't anywhere near the power button on the left, but I'm getting nothing out of the power button. It has the click so mechanically it seems fine, but it does nothing at any time. No visible damage or corrosion. The Touch ID is also giving a "Fingerprint Limit Reached" error even after running xartutil ?erase-all in Terminal but I'm not sure if that's related. Any idea where to start with this?
