Windows 7 won't automatically go into sleep mode.

I have a windows 7 PC with Asus m5a99fx motherboard. I can go into sleep mode manually from the shutdown button, but it won't go automatically from setting it up in power options. I have tried going to Advanced Settings and adjusting multimedia settings, and turning off Media Streaming in network settings. Nothing has worked to allow auto sleep mode. I also have the latest driver for my ATI Radeon HD 5450 video card. When I go to CMD and put in "powercfg -energy" I get a message that says energy efficiency problems were found, 8errors, 4 warnings, 14 informational. Anyone have any suggestions?

If you have a programmable keyboard or some other convenient way to launch commands you can use this command to put your system to sleep immediately:

rundll32.exe powrprof.dll,SetSuspendState Sleep

Other options to troubleshoot Power Options and Sleep Mode Problems.

If none help then try an earlier Display driver. Did it work before?

You can troubleshoot it through each step by setting Sleep to 1 minute timeout and waiting to see.

I'd also enable Hibernate and set it for 2 minutes to test. Hibernate is preferred anyway since it saves your work before powering down but powers up twice as fast. I set my installs to Balanced Plan with Sleep at 30 and Hibernate at 60 minutes. Hibernate - Enable or Disable

I know you probably fixed it or went bald, but I was so pissed at this problem and you had exactly the same symptoms I just had to make an account and leave it here.

My problem was exactly the same but let me recap:

Wasn't keyboard.
Wasn't mouse.
Wasn't multimedia.
Wasn't network.

No wake_armed.
Last wake was empty.
Restoration of policies didn't fix it.
I went through every listed HID adapter to see if anything was checked.

Turns out this guy on the link had the same problem 7 years ago and it was simply the hybrid mode that was making his life a living hell and so was mine. It is suspending just fine. Hope stays like that.

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, but it does neither of those. No screensaver after 10 minutes either like I said.

"powercfg lastwake" does not work either. it always says

"C:\Windows\system32>powercfg lastwake
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


C:\Windows\system32>powercfg -requests

I get

DISPLAY:
None.

SYSTEM:
None.

AWAYMODE:
None.


C:\Windows\system32>



So there is nothing waking it up, there is no requests preventing the computer from sleeping, yet it still will not sleep.

I am ripping my hairs out on this one

this was my solution and the problem was a flash game page that was open and playing sound and that has been prevented the pc to go to sleep, thanks Sylveon Fetish with your useful commands:
powercfg -requests
powercfg lastwake
