Tried following these instructions: http://helpdeskgeek.com/windows-7/windows-7-will-not-sleep/
I have tried all these things and everything found on all websites Google lists on this problem and yet my Lenovo b570 still will not sleep. Does not even initiate screensaver, display does not turn off, nothing. shutting down/restarting makes no difference. still does not sleep. It is set to sleep after three hours and to turn off display at 30 minutes, it is supposed to dim the display after 15 minutes, but it does not do any of those. No screensaver after 5 minutes, screen does not dim after 15, display does not turn off after 30, and the computer definitely does not sleep after 3 hours
"powercfg lastwake" does not work either. it always says
Wake History Count - 0"
so nothing is actually waking it up, it just refuses to sleep, display screensaver, turn off screen, or sleep
and when I type
So there is nothing waking it up, there is no requests preventing the computer from sleeping, yet it still will not sleep even told to after being idle for said amounts of time. and I do not even get a screensaver,
so something in oblivion is keeping the laptop awake that is beyond me and beyond the reportings of CMD.
I am ripping my hairs out on this one
