Since I’ve updated to High Sierra, I have noticed that my laptop, after a time, doesn’t go to sleep anymore. Once I rebloot, if I walk away for a bit, it sleeps as it should. However, after a few days of not reblooting, I notice that it’s always on (regardless of whether it’s plugged in or not. If I don’t plug in power cord and walk away for a few hours, I’ll come back to a low or empty battery). Is there a way to tell which app or apps are keeping it from going to sleep?
