So before posting on the forum, I searched google and found various articles on the topic. Using Windows 7.
I used powercfg /lastwake to determine which device brought the computer out of sleep and here's what I got:
I do have a USB 3.0 powered hub connected so I went to the Device Manager and in addition to everything else, I see 4 "USB Root Hub" items. I went to the power management tab of all 4 of those. They all have "allow the computer to turn off this device to save power" checked. And none of them have "allow this device to wake the computer" checked. Also, that option is grayed out so I couldn't check it if I wanted to.Code:Wake History Count - 1 Wake History [0] Wake Source Count - 1 Wake Source [0] Type: Device Instance Path: USB\ROOT_HUB20\4&36206eee&0 Friendly Name: Description: USB Root Hub Manufacturer: (Standard USB Host Controller)
The instance path in the info above matches the device instance path of the second USB Root Hub in the device manager
Any suggestions on what to do? Could the option to turn off the device to save power be what is causing it to come out of sleep mode?
I've also attached a screenshot from the device manager of all my USB devices.

There may be a problem with the usb 3.0 hub. I have had problems with USB 3.0 devices, including hubs, causing more than just waking up. You might try unplugging that hub and see what happens. Also other devices which normally wake a PC like mouse, keyboard and lan (disable).

The Roothub devices refer to your internal USB ports. So they shouldn't (in theory) have anything to do with your external powered hub.
If you try (as Budman suggested) unplugging the external hub and it still does the same thing, then you know it's the internal port. There could be a glitch in the configuration settings.Try uninstalling and reinstalling the offending device.
- In Device Manager, right click on the USB Root Hub and hit Uninstall.
- Restart your computer and it should automatically detect the device and reinstall it.
If you try unplugging the external hub and it fixes the problem, try connecting it to a different port and see if it wakes up again.If it does, check if the instance path in /lastwake changes.
If you discover that it's the external hub that's waking it up, and reinstalling it in Device Manager doesn't solve it, try connecting a different powered hub to the computer and see if that also wakes it up. If it does not, then you've narrowed it down to a hardware problem with the first powered hub.- If so, then you know it's the external hub, and your internal ports are allowing the wake signal to get through. Look in Device Manager for a "Generic USB Hub" (that's the external hub) and make sure that does not have "Allow this device to wake the computer" checked.
- Try un/re-installing the Generic USB Hub device.
- With the external hub plugged in,
- In Device Manager, right click on the Generic USB Hub and hit Uninstall. If it gives you the option to also remove the drivers, click Yes.
- Unplug the hub from the computer while it is uninstalling the drivers (to prevent the computer from trying to re-install it before you have rebooted).
- Restart the computer.
- Plug the hub back in, and it should re-install it.
- If that makes it wake up again, then again, it is the first port that is the problem, and you should try to un/re-install the USB Root Hub as I mentioned above.
Do or do not. There is no "try." - Yoda -
Thank you for the information. I think I may have solved the issue. Not sure how I missed it, but in the power settings, allow wake timers was set to enable instead of disable. I set to disable, and the computer was still asleep this morning. Will wait and see if it continues to work, otherwise I'll refer back to your post
