Low Power Modes

I have seen a couple of posts regarding Low Power Sleep modes. None of these seem to lead to any answers that explain how to put the Dash or Dash Pro into Low Power mode. From the Arduino IDE, is there a call to put the Dash into the lowest possible power state and then wake it via pin?
