Out of guesses It could be a service that's failing to start, but I don't know which one that would be without time to experiment.

You might try starting a whole new thread with a title such as
Yoga 510-14ISK Hotkey Popup Notifications missing
Or words to that effect. State in the first post that your hotkeys - Camera, microphone, airplane mode - all work normally, but you're not seeing any notifications on the screen.
Good luck. I'll keep looking.
