I have found out what is waking my computer up 1 minute after I click sleep. My Microsoft dual receiver wireless keyboard (mouse and keyboard center) in device manager is the culprit, according to
powercfg devicequery wake_armed.
If I uninstall it, my computer sleeps like a baby, but then I have no keyboard. Does anyone know how to troubleshoot this? I can disable it completely but that doesn't work. only uninstall gets my rig sleeping peacefully.
