Hello Ed1-US
Sorry to hear about these notifications. Thanks for reaching out to us.
Restart Surface Book. Check manually for any additional updates, and verify that everything has installed successfully.
Eject the Clipboard from the Keyboard. Inspect the connections for any debris or corrosion.
Does Keyboard loose functionality when this message appears? Does Surface think it has detached?
Best regards
