  • Surface RT or Surface 2: No power button on start screen
  • Surface 3: No power button on start screen
  • Surface Pro or Surface Pro 2: Power button on start screen
  • Surface Pro 3: No power button on start screen
Note The images that ship with the Surface 3 and Surface Pro 3 are configured to show the power button. This is a customization that is included with the image.
