Windows 10: What is 'Waking' my PC?

I have been putting my computer to sleep yet at around the hours of 10pm-12am MST all of a sudden it wakes up.


I have disabled my mouse and keyboard both from being able to wake the device, as well they both get turned off and are not on when the PC suddenly wakes itself.


How do I find out what is waking my machine so I can prevent it?

Troubleshooting PCs spontaneously waking from sleep

First off: I tried disabling wake-up by the mouse on both PCs and disabling USB Selective Suspend too, to no avail.

Thanks, I'll definitely look into that. Good to know that powercfg can list all wake-enabled devices, 'cause when I went through all ... eight-ish PCI-to-PCI bridge devices in Device Manager, none of them had wake events listed (in the "events" tab under Properties), which doesn't quite add up with one/more of them waking the PC a dozen or so times over the last few days. Of course, they don't even have the option to enable/disable waking the PC in the properties menu. I'll take a look at disabling a bunch of stuff through powercfg once I get home from work.

Sorry if I came across as rude, but honestly, your reply did not at all indicate that you'd read my post in the first place. I said I'd been looking at wake-up history in the Windows event log, and I listed several of the devices cited there as having woken up the PC. If you came away with the impression that I hadn't investigated this thoroughly, I suppose I might not have been clear enough, but it's all there in the post. While powercfg does give out some more detail (device IDs and such) than Event Viewer, it only lists the last wake-up, and as such doesn't really help in this instance, as it's clearly not a single device at fault, and tracking wake-ups over time seems more useful. Also, figuring out how to view wake-up events in the Event Log is what you do after you've concluded that powercfg isn't giving you enough information *Wink
