Tried VoodooPower as suggested. Didn't help. I could always shut down and reboot fine. I just can't sleep. Since I don't want this thing running 24/7 and hate having to boot up twice a day, I really wish there was a good sleep solution. Especially since a cold boot often fails and leaves me with a blank screen and mouse cursor instead of a login box. Hitting the reset button to reboot fixes that, but it's yet more delay.
