The board is in a new, flawless condition even under a microscope. It is obvious that the problem is with the board, but what exactly needs to be looked at or replaced?

I have 3 of these MacBooks and I noticed that I can neither turn them on nor turn them off using the power button. However, when booting in safe mode, the sensor works.
