I have Windows 8 running on a DH77EB motherboard. I haven't been having issues with it until the last two weeks or so. I have lost power at my home due to storms several times in the past few weeks and thought at first that this was what was causing my computer to fail to wake from sleep. I would find my computer with the HDD LED solid and it would not respond until I pressed the reset button.
I tried to test the system by manually entering sleep mode. The fans kept running and the HDD LED once again became solid. I then updated the BIOS from 100 to 101. I don't think that had anything to do with my issue, but after the update, I noticed that my computer was then able to enter sleep mode, but would wake up on its own within a few seconds. I ran the command "powercfg -lastwake" and found that my network adapter is what woke the computer. From device manager, I disabled the option for the network adapter to wake from sleep and tested the computer again. It woke immediately again. This time, the -lastwake command showed that the USB 3.0 eXtensible Host Controller was responsible for waking the computer. From device manager, there is not a Power tab from the properties for the USB3.0 host controller. When I run the wake_armed device query, it only shows my mouse and keyboard as wake armed.
Can someone help me to keep the USB 3.0 host controller from waking my computer from sleep?
