Hi N1CKL 809,
Thank you for reaching Microsoft Community. I understand that you're experiencing issues with your Surface Book 3 where the screen keeps on detaching and causing the system to crash. Based on the symptoms you've described, it's possible that this could be a hardware issue with either the base or the screen. However, before we jump to any conclusions, let's try some troubleshooting steps to see if we can resolve the issue.
First, let's try resetting your Surface Book 3. To do this, press and hold the power button for 30 seconds, then release it and wait for a few seconds before pressing the power button again to turn it back on. This will reset the device and may resolve any software issues that could be causing the problem.
If resetting your Surface Book 3 doesn't resolve the issue, kindly try these steps below:
- Check for updates: Make sure that your Surface Book 2 is up to date with the latest software and firmware updates. To do this, go to Settings > Update & Security > Windows Update and click on Check for updates. Install any available updates including Optional updates.
- Run the Surface Diagnostic Toolkit: The Surface Diagnostic Toolkit will run some system checks and repairs on the device. See: Fix common Surface problems using the Surface app and Surface Diagnostic Toolkit - Microsoft Support
- Uninstall and reinstall Surface DTX: Follow these steps below:
Open Device Manager
Expand System devices
Right-click on Surface DTX
Select Uninstall device
After uninstalling, restart the Surface to reinstall the driver
Let me know how it goes.
Kind regards,
Marrion
