Hi Penny,
The screen of your Surface Pro 4 could be shaking because of software or hardware issues.
Here are some solutions that may help you resolve the issue.
Force shutdown your device.
- Press and hold the power button on your Surface for 30 seconds and then release it.
- 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. 3. After you release the buttons, wait 10 seconds. 4. Press and release the power button to turn your Surface back on. You should see the Surface logo.
