Jetson TK1 auto power on after power failure

Hi, I have several TK1s which automatically power on whenever I switch off the power and switch it back on. (this is what I want to happen; i.e. in case there is a power outage TK1 boots up again automatically). However, one of my TK1s does not automatically power on and I need to press the power button on the board. Does anyone know how make it automatically power on (without pressing the power button) when the power is restored.
