On Windows 8.1 my computer didn't resume from sleep automatically. it stayed asleep... On Windows 10 something is causing my computer to resume from sleep. I've disabled all wake from sleep options for every device in device manager such as mouse, keyboard, etc... I've disabled the Windows 10 maintenance program In event viewer the wake source is always 'unknown'. I've disabled wake on LAN options on the network adapter. I've disabled wake timers in power options. I've checked powercfg -lastwake and it doesn't show what was the cause I've checked powercfg -wake_armed and I've disabled everything there I've checked scheduled tasks and nothing. Still Windows 10 keeps resuming... Anything else I should check? Could this be a driver issue?
