If you’re Surface Pro 4 is having issues shutting down, normally you would initiate a shutdown manually using the power button by holding it down. Sometime however this doesn’t work and you will need to initiate a two button shutdown.
- Hold Down the Volume Up Button
- Whilst Holding Down the Volume Up Button, Hold and Press the Power Button for 15 seconds
IMPORTANT: You may notice that the Surface logo comes up on the screen during the power down. Do not be fooled thinking that the Surface has shutdown properly.
DO NOT RELEASE THE VOLUME UP AND POWER BUTTON UNTIL AFTER 15 SECONDS
If by chance you released the buttons as soon as you saw the Surface Logo come on the screen simply start the process again.
