Troubleshooting a Windows 7 PC that wouldn't sleep
My Windows 7 system resumes from sleep a few seconds after I've asked it to sleep. I have stopped all the wake devices I can in Device Manager from waking the system. The system log shows an event that says: Wake Source: Device -USB Root Hub. I cannot prevent the USB Hub devices from waking the computer, there is no such setting in their properties.
Any ideas how to get it to sleep?
