However with that particular problem powercfg -lastwake often comes up empty after a wake thus providing no insight on what caused it. InvestigationWhen it comes to power management Windows has a useful command line tools named powercfg which can be used to diagnose and fix issues. That's often caused by power requests issued by drivers such as a Sound Blaster card doing Dolby Digital Live or a faulty web browser thinking it's downloading something when it isn't anymore, Vivaldi I'm looking at you. Sometimes Windows just does not go to sleep after the specified period of inactivity. While most frustrating it did provide me the opportunity to identify the problem since I could easily reproduce it. I was once in a situation where it would wake up instantly after going into hibernate. Windows would wake up after anything from a few minutes to a few hours of sleep. SymptomsIn the more than two years using Windows 10 I've had various manifestation of that problem. Microsoft Windows team is really showing negligence and incompetence there.
At time of writing the last post on that massive thread was from just three days ago, that is the 15th of November 2017. It's not like they don't know about it's been reported soon after release on August the 10th 2015. Moreover Microsoft inability to tackle those issues over 2 years following the initial release is plain disrespect for their customers and users. Why on earth would Microsoft ship its flagship product with such blatant problems is beyond me. RantFirst of all I believe such an issue deserves a good rant. Until recently I was not able to investigate that problem thoroughly, this is about to change. Not everybody can afford 6 bedrooms mansions, dear Microsoft executives.
Yes, sleeping next to your computer is a valid use case. Most annoyingly it tends to happen in the middle of the night so that if someone is sleeping next to the computer it will no doubt wake her up too. Out-of-the-box my brand new desktop Windows installation has the bad habit to keep waking up from sleep or hibernate for no obvious reason. Purpose & ScopeThe most annoying issue I've had since upgrading from Windows 7 to Windows 10 in the summer 2015 has been the inability of that system to remain asleep.
