Black screen every Thursday, PC quit sleeping this past week.

Ok, I've been busy, but I set the power plan to defaults today, rebooted, then forced sleep. What did it do? Right in front of me, it goes to sleep, I hear the PC click, the wattage on the UPS meter goes low, THEN I hear the drive spinning up again and the screen comes back on!

So I just ran powercfg and got:

Here's what you want to see on the Power Management tab for the corresponding device. If you have multiple USB root hubs, make sure this applies to ALL of them.
HTH,

Ok, just did a bunch of them and switched them to not allow, like you show, then forced sleep and it did the same thing - shut down and immediately woke back up. Arghh... STILL showing usb root hub as the culprit. WTF???

Thanks Ed. @EdTtittel

IN my opinion these should all be centralized in Advance Power Mgmt settings under some new heading.

MamaBear as we could be hunting these for a long time, lets head back to powercfg and type

powercfg devicequery wake_armed

and

powercfg devicequery wake_programmable

Windows will then report, to each query, all other items with this ability and we can address as required.

Ok, I just entered both of those, but am not sure how to read the results now. Will try the forced sleep now...

This is interesting. The host controller may be on the motherboard itself? I checked this and found that the driver hasnt updated since 2006. Is this PC THAT old? It was refurbed when I bought it, but I don't recall the year.

The controller is indeed on MB. Lots of old drivers are still in use. You could try updating driver but make a restore point before you do this.

I tried but it says I have the latest.

This makes no sense, though, as it wasn't doing this before that last update. It was sleeping fine before that - the original issue was black screen and unresponsive.
