Hello lp-c,
Thank you so much for posting in Microsoft Community.
I appreciate you raising this concern and I understand that you have seen changes on the device name of your Surface.
Basically, it is not normal for the device name to change after a reboot or hard reset. The device name is usually set during the initial setup process and should remain the same unless you manually change it. However, it is possible that the device name was reset to its default name after the hard reset. You can try changing the device name again to see if it sticks.
To change the device name on your Surface Book 3, follow these steps:
- Open the Start menu and click on Settings.
- Click on System.
- Click on About.
- Click on Rename this PC.
- Enter the new name you want to use for your device.
- Click Next and then click Restart Now to apply the changes.
If this doesn't work, try resetting your Surface again and see if it helps.
Please let me know if this works.
Best regards,
Rolando S.
