I really do not understand Windows 10. It really seems like Windows 10 laptops and PCs are unable to sleep. They keep waking up, and then refuse to sleep. Frequently I find my work laptop in the morning turned on by itself, screen on, fan blowing enthusiastically. Power management in Windows 10 seems to be utterly broken. It certainly doesn't obey any of my settings.
