I tried it twice and I don't see any reaction from the SP3, apparently I'm not the only one case.
Two-button shutdown
Use this two-button shutdown process to ensure that your Surface is turned off completely. Here’s how:
Step 1: Press and hold the power button on your Surface for 30 seconds.
Step 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.
Step 3: After you release the buttons, wait 10 seconds.
Step 4: Press and release the power button to turn your Surface back on.
- If Surface turns on. The battery might be very low and will need to charge for a while. When it has at least a 40 percent charge, install the latest Surface and Windows updates to help prevent future problems.
