How can I unfreeze my Surface Pro 3?

To unfreeze your Surface Pro 3, press and hold the power button for about 10 seconds until the device turns off. Wait a few moments, then press the power button again to restart it. If the device continues to freeze, consider performing a hard reset by holding the power and volume-up buttons simultaneously for about 15 seconds until the Surface logo appears. If problems persist, you may need to check for software updates or perform a system restore.
