i have used every powercfg command under the sun and spend 2 weeks on other forums trying to trouble shoot and nothing. nothing. the international forums have stopped talking to me. there's nothing they can do. not even dell and asus technicians.
i have a laptop that -requests showed nothing and would not sleep. until i restarted it, then it slept. so it cannot resleep. only once or twice.
then i have a tablet that has this thing called standby connected. if you leave it long enough (hours) it will sleep. if you press the sleep button it won't sleep. pain in the @#$%. i have given up on the tablet. apparently it does that sometimes.
