Windows 7: Homegroup Setup O.K. - now Computer won't Sleep

Have you done any BIOS updates?

See:
Sleep and hibernation: frequently asked questions

It says that there can be a setting in the BIOS for sleep states.

Wake on Lan (WOL)

I'll post you a link for definition of WOL.

Wake-on-LAN - Wikipedia, the free encyclopedia

If you are not waking your computers via the network you should not need WOL. Therefore you can disable it on your adapters. By waking I mean if you are at one rig and you want to access files on the other rig and it is in "sleep" you have to send a WOL signal to access it. If they are both awake you don't need the WOL signal. Never the less a path forward for you would to be get all the settings correct so that your rigs will sleep. Then if you want wake on lan you can find the correct setting for that.

Also Dave's idea to check the bios is appropriate. You will probably find power settings relating the the different sleep states such as S1, S2, S3 etc.

Thanks you guys. I'm not sure if I should disable WOL right now. For the purposes of simplifying things maybe I should. But it would be nice to have that functionality.

I updated my BIOS months ago to the latest for the board. All went well and I was able to Sleep for months afterward. I disabled Hibernation soon after the first POST.

In the BIOS I've always run S1 and never had an issue. I will double-check everything to make sure.

I did Clear CMOS recently. I had updated the RealTek Network Adapter and was getting this annoying "Press Shift+F10 to configure" message during POST. Once I cleared CMOS it went away.. But I reset all the power options to my normal setup.

My "normal setup" in the BIOS includes "Wake up Event by" and the choices are BIOS or OS. I've always had it set to BIOS. Could that be causing the issue? Should it be set to the OS?

I'm looking thru the BIOS now - on the workstation - and I see one more thing that may be pertinent: the "Resume S3..." choices. There are 5 in total:

Resume S3 By USB Device - Enabled
Resume S3/S5 By PS/2 Keyboard - disabled
Resume S3/S5 By PS/2 Mouse - disabled
Resume By PCI-E Device - disabled
Resume By RTC Alarm - disabled

Those settings have always allowed me to Sleep prior to setting up the Homegroup. Strange how there's no mention of S1... but like I say they've always worked before.

Thanks again for the links and for your help - I appreciate it very much.

Update: Still won't Sleep

I disabled the adapters I'm not using.
I disabled Shutdown Wake-On-LAN, Pattern Match and Magic Packet.

sure wish I could figure this out...

I don't see what kind of mouse you are using. If it is a wireless laser mouse If you have a strong desk light it could be inhibiting sleep mode. Just trying to help.

Thanks HH - no suggestion is a bad one. However, the workstation used to Sleep just fine before I setup the Homegroup.

I have a feeling the solution is somewhere in the Power Plan Options.

POWERCFG (from the CLI) has excellent diagnostic tools but at this point I've learned everything I can from them. Unfortunately I don't have the expertise to fully evaluate all of the results. The ones I do understand haven't help me pinpoint the solution.

Anyway, thanks for replying and if you think of something else please don't hesitate to post it. I welcome any advice on this problem, and I'm grateful to you all for taking the time to help.

ps - if anyone knows POWERCFG I would really like to ask you a couple questions. Thanks!

While you are contemplating your next move, run sfc /scannow at an elevated command prompt to see if your have any corrupted files.

I was about to suggest powercfg at an elevated command prompt but you posted you have done that?

One trick i have seen work is to set something to default and let it save then change things to what you want. In other words set your current power plan by clicking "set to default" then reboot. and try to get it to sleep.

Powercfg

At an elevated command prompt what does "powercfg -LastWake" return?
What does powercfg -waketimers return?

Good thread:

Stopped Sleeping.. powercfg report included

run at elevated command prompt:
powercfg -energy -output %userprofile%\desktop\energy_report.html

That should put a report on your desktop for us to read.

Thanks again H -

I've run the powercfg commands again -

lastwake reported "USB Composite Device" and that's my mouse/keyboard - as expected

-devicequery wake_armed reported the Logitech keyboard/mouse - again, as expected

the -energy report listed 14 "errors" but none of them appear related to preventing Standby.

NVIDIA released another driver for my GTX 470 so I'll update that now...otherwise, I don't know what else I can do besides what you suggested, going back to a default Power Profile, deleting the Homegroup and starting over.

I've run the sfc utility and no problems were reported.

One question - do you enable S1 or S3 in your BIOS? I always heard S3 was unstable and that most users preferred using S1.

Thanks again for your help!

S3 is the preferred sleep state. That's what should be enabled in BIOS if you want to use hibernation and sleep.
