Windows 7: Machine not going to sleep properly

Machine not going to sleep properly

The machine is the MAINGEAR machine listed in my system specs.

The screen is going blank after the set 30 minutes but, the machine isn't going to sleep. I can make it go to sleep by choosing "sleep" from the start menu but it won't go to sleep automatically like it's supposed to.

I started noticing this behavior after I changed the computer's name from "WINDOWS7DESKTOP" to "MAINGEAR-desktop". I received a message telling me the name was too long and it would automatically be shortened as needed and something else about what problems might occure. I guess I should've paid a bit more attention to the warning.

Now, the machine won't go to sleep like it's supposed to.

The reason I think the name change might be related is, I was trying to edit one of my created events in the Task Scheduler. I couldn't edit the event because it was associated with with the old name. I hade to delete the event and re-make it.

Anyone know what I might have caused by changing to machine's name and how I might be able to fix it?

EDIT:

I guess I could maybe just change the name back? I don't really want to do that. I have multiple machines (2 X WINDOWS7DESKTOP) and I need distinct descriptors.

If you choose something 15 chars or less, you should be OK - although I've never heard of simply changing a machine name causing this issue, I suppose anything's possible. Would be worth a check just to be safe, of course.

What could cause it?

Hard to say, especially if forcing sleep works. More than likely, it's something keeping it awake, but what that something is isn't necessarily easy to figure out. You could run powercfg -energy and let that run to see if it finds any devices that will hamper sleep or hibernate, though, as a first step.

Will do as soon as I get home. But, to clarify, Start>Run>powercfg -energy? Or do I just type powercfg -energy into to search field and hit enter?

Open an Elevated Command Prompt to type it in.

Have you checked optional Windows Updates for newer drivers? This issue is almost always Display driver so try a newer or different one.

You can also find clues by checking your Performance log: troubleshooting steps

Results of powercfg -energy:

Quote:
Energy efficiency problems were found.

23 Errors
2 Warnings
20 Informational

See C:\Windows\system32\energy-report.html for more details.
I've attached the energy-report as a .txt file

Looks like some USB device(s) but how in the world do I know what?

Also the note about ACPI _PSD Object Failed Validation and needing to update my BIOS kinda freaks me out.

I just did a clean install on this system less than a month ago.

EDIT:

OK, this is what really ticks me off! I look in the device manager and see yellow triangles on 2 USB devices and 1 on the 80211 n WLAN device. I see the message that says, "The drivers for this device are not installed. To find a driver for this device, click Update Driver." I do so, but am returned with the message, "Windows could not find driver software for your device." Or, the one I really like, "Windows has determined that the driver software for your device is up to date." Then why is it telling me I need to update the darn thing? Grrr!

EDIT 2.0:

I got the Wireless driver installed and that yellow triangle for that went away. I have no idea where to start with the USB stuff.

EDIT 3.0:

The only optional update available was for MSE definitions.

Well, FWIW I don't think that changing PC names is at issue here either, though as cluberti said "anything's possible". Windows 7 Sleep functionality can be the most aggravating aspect of Windows ever...

Look at your Power Options under Advanced settings and see under USB settings if you have selective suspend disabled. In any case change that setting and test some more--maybe you'll get lucky.

I have set the Sleep timer to 1 minute and then babysat the PC while killing running programs, processes, and services (in that order). Good luck.

Thanks for the reply, maxseven. However, after having looked at the powercfg and a wellness report as suggested by cluberti and gregrocker, I think I may have other issues. I'm wondering if I should start another thread to address those?

What gets me is, everything was working fine.

BTW, I changed the machine name back to what it was in the beginning but, I don't think that mattered in the first place.

As you doubtless know, the problem with Windows is you can get started down a path ("fixing" stuff) and end-up making things worse. Before you do that is there any chance you have a System Restore Point you can revert to?
