On occasion my computer won't sleep or shutdown when I tell it too. It will turn itself back on immediately. I upgraded to W10 from W7 back in August 2015. This was never a problem until recently. I check for pending updates when this happens, and there are none showing. If I wait 15 to 30 minutes it is no longer an issue. This doesn't happen everyday. Only once or twice a week. Anyone else notice this type of behavior?
