  1. Press and hold the power button on your Surface for 30 seconds and then release it.
  2. Press and hold the volume-up button and the power button at the same time for at least 15 seconds and then release both. The screen may flash the Surface logo, but continue holding the buttons down for at least 15 seconds.
