Sleep mode randomly turning on

I haven't seen it happen on mine. Probably time to call Garmin support.

Yes, this does also happen to mine and it's pretty annoying. Because even when you press "wake up" and manually disable it, it still turns on automatically again sometimes... I feel that recently it doesn't happen that frequently though.

There was another thread about this that got no traction. In my experience it happens if you manually disable sleep mode "a long time" before your planned sleep schedule ended. I say that because if I wake up, say 1/2 hour before it stays manually disabled but if it is an hour or two before it starts turning sleep mode back on after a while. Not a very scientific response, I know

I don't believe that it's related to the sleep schedule... in my case this happened outside the sleep schedule for sure... otherwise I would just disable / adapt the schedule and only activating it manually, which I didn't try... yet... well if it happens again I'll give that a go...
