Trouble with S3 sleep on windows

[statik213]

Hi guys,
I'm having trouble getting windows 7 to go to S3 sleep on my i7 860 / ASRock P55 Pro rig.


When I hit the power button, the system powers down and then comes back on immediately with all the fans going at 100% and stays that way.

At this point if I hit the power button, nothing happens. Holding the power button down kills the system. Pushing it one more time brings it back up and windows "resumes" successfully. I'm guessing the resume is from a hibernate... I think vista/7 do standby+hibernate when you tell it to sleep.

So the whole sleep thing is a complete fail for me, since it was just coming back from hibernate. And the system didn't exactly power-off since the fans came back on and kept going.


I've spent a lot of time trying to figure this one out. I ran across this blog posting about similar issues.

I downloaded the MS tool dumppo and ran it and I got this output:
D:\bin\Standby Util>dumppo.exe admin
Admin policy overrides
Min sleep state......: S1
Max sleep state......: S4 - hibernate
Min video timeout....: 0
Max video timeout....: -1
Min spindown timeout.: 0
Max spindown timeout.: -1


It seems that I'm having the problem the guy in the blog posting is talking about. I tried setting min sleep to s3 w/ dumppo in admin mode, but the value is not being preserved across reboots and isn't active until a reboot. So that seemed to be a dead end.
Note: I don't remember if I had enabled S3 during the windows 7 install. It's on now though and doesn't seem to do anything.


One other potential problem I can think of is the asrock instant boot feature. It does some tricks w/ the S3/4 states to get you to a windows desktop fast from a cold boot by sleeping somewhere during the windows startup cycle. I think it might be 'cos of that because the fans go from mid-rpms to off to full-speed, as if something brought it back from sleep.. THere don't seem to be any bios options to disbale this feature. I haven't installed any of the instant boot software.



I'd appreciate any help w/ this issue... Anyone else had any issues w/ asrock boards?

I think that could be it. I remember my ASrock board in the past behaved similarly and confused me. I just used InstantBoot like S3, iirc. In your case it's obviously not working since fans are running at full throttle.

What happens when you click "Start -> Sleep" instead of pressing the power button on the case?

Same thing... doesn't seem to have any affect. I didn't install any of the instant boot stuff. So I have no idea what's going on.
