You’re most welcome, David. Yes, it is also a possible hardware-related issue. If in any case that you’ll still experience the same issue after following the troubleshooting steps mentioned above, we recommend that you perform a fresh start in your device. This is the least intrusive form of reset. It is a Windows feature that installs the most recent version of Windows. Fresh start retains all of your personal files and some Windows settings. Fresh start also keeps any drivers that you installed. To do this, kindly go to Start > Settings > Update & security > Windows Defender (Windows Security) > Device performance & health. Under Fresh Start, select Additional info > Get Started.
If the issue is still persisting, then it would be best to reset your Surface Book 2 using a downloadable recovery image for your device. Kindly observe if the issue will continue to exist.
We appreciate your patience.
