Lol, yep. My Win 10 desktop will suspend just fine, but then it wakes itself up for no apparent reason and just stays running indefinitely after that. I can't figure out what the cause is, but I've taken to just shutting it down in between uses.
I'm a frequent sleeper and I depend on the feature. Next time your machine wakes up by itself, go to a DOS prompt and type "powercfg -lastwake" That will tell you how it happened.
For me, part of the solution was to go into the device manager and edit the properties for my mouse and my network controller. On the "power management" tab I disabled the "allow this device to wake up the computer" option. I only use the keyboard to wake the PC.
Additionally, when I left the machine sleeping overnight, there was some scheduled task that would occasionally wake the machine. There is a way to disable that, but I forget the specifics.
My computer does it, and typing in powercfg -lastwake just says "unknown source". I've disabled every wake event, update service, wake-on-lan, disabled the ability of my mouse and keyboard to wake my computer up, and it still does it.
This. I was playing Starcraft before bed, and just shut my laptop to suspend it... it was suspended until about 4 hours later, when, in the middle of the night my wife and I were awoken by sounds of zerglings dying. Very unpleasant, and quite surprising.
I've been fighting with this literally since Windows 10 came out. My desktop PC wakes up every night, around midnight/1am, and will not go back to sleep. I've disabled everything single wake event in windows, there is no wake-on-lan(as a matter of fact it does it with lan unplugged and ethernet disabled). Looking in the power events just says the computer woke up due to "unknown source". It does not do it with Windows 7.
I had the same issue. I think, your keyboard/mouse are allowed to wake up from sleep automatically and some glitch gives your desktop the impression that a key was hit. If you disable this in the device manager, this issue should be resolved.
