i have 2 devices with the same problem. had one last month, customer needed to backup his data - so he took the device as soon as he saw apple logo (in urgent cases i allow customer to see the process)
power button does not work, kind of shorted but not. call me dumb, i do not get it.
SMC_ONOFF high on board with trackpad+keyboard attached, no reaction on the power button, ALT+CTRL+SHIFT resets SMC as if the power button was pressed.
ejected power button, 0.3v on pads, resistance 500kohm connected/unconnected.
traced smc_onoff to the trackpad has no direct trace to a keyboard button.
works perfectly fine with SMC_ONOFF pads - turns screen on and off, shuts down the device after 8 seconds, works fine with and without keyboard attached.
