Won't sleep - just goes back to desktop

I select sleep, screen goes black, then almost immediately goes back to desktop.
This is only on new 'official' install - worked fine in RTM leaked.
I did an powercfg /energy report and it finds errors in just about every USB device. (attached report)
Don't know what is going on!

Well, I could be wrong but just suggesting.

Check that in your BIOS if the "Wake Up on LAN" is ON. If it is, turn it off. It can solve the problem.

It might also be you NIC card (had this happen to me a while back..)

Go to Device Manger select you NIC card(s) and go to the Power Management section..and uncheck Allow the device to wake you computer..

About the USB problem (I don't know)The only thing I could think of is go and look at your USB controllers(In Device Manger) and see if any of them have power management If they do check to see if the box is unchecked..the Allow the device to wake your computer..

Hope this Helps..

For what its worth, I have never had much luck with sleep over the years.
I turn off my monitor when done computing and leave it at that.

Thanks guys. I had already checked all that.
The network adapter is not set to wake the computer, and none of the USB devices are either.
I did a terminal command to identify which devices can wake up, and it was only keyboard and mouse - as it should be.
All the 'wake up on' BIOS settings are disabled to.
This is weird. After many months of W7 beta, RC, numerous builds, RTM etc. with everything being OK, suddenly I install the release version (just in case!) and now sleep doesn't work.
I'll have to get this working because switching on and off is a real pain.
PS. OSX86 sleeps perfectly well too.
Any other ideas?

I had a lot of trouble with this a while back...Don't know if it will help you but for me upgrading my video drivers solved my sleep problems. New Nvidia driver 191.07 to be exact as I see you use an Nvidia card.

Also check out Brinks tutorial on sleep issues: Power Options and Sleep Mode Problems - Vista Forums

Thanks again, guys. I am already using the 191.07 driver and I have already been through Brink's excellent guide - on more than one occasion - and everything checks out there.
No change. Just doesn't work.
It's like it's not actually trying. Screen goes black for a second and then just returns to desktop.

Any chance you can remove all unnecessary hardware to do some testing? Remove the NIC, wifi, USB devices, etc? Remove everything except for the keyboard and mouse to see if it's a piece of hardware causing your sleep problem.

OK, I removed all hardware, i.e. ethernet, all usb devices except keyboard and mouse.
Still no go.

Has no-one got any further thoughts on this?
It's driving me mad!

It might be poorly written chipset drivers, or a problem with the OS interacting with the BIOS. Do you have any updated chipset drivers available, or perhaps a BIOS update available?

Thanks for that.
I am on the latest Asus BIOS for the P6T Deluxe V2.
I tried to install the Intel ICH10R drivers v 9.1.1.1014 but the setup file didn't seem to do anything. It says they were installed, but it was too quick!
How can I check in Device Manager if the latest version has been installed?
As I said in an earlier post, I didn't have this problem until I installed the actual retail version of W7. All other builds were fine, and also OSX86 sleeps perfectly too.

Um well im sure this has been in brinks guide but power options go to change plan settings then go to changed adv power settings scroll down to multimedia settings and on there for the setting select, [allow the computer to sleep]. It helped me out on vista but then waking up from sleep on that was a pain having to pull usb plugs so i never used it. Now im happy that it works on W7, i hope it can work for you.


*Also trying posting your settings, so we can see it, not that it might help .

I have the same settings as you and the problem is the same.
Select sleep, screen goes blank, and immediately just returns to desktop. No other activity at all.

I have a similar issues with my MSI Wind U100 netbook, ever since Windows 7 came out it has had trouble turning off the screen or going into sleep mode.

Seems like a video card issue, even with the latest drivers installed for Windows 7.

[Try] the USB selective suspend setting disabled, based on looking at your report with the Errors.

I also noticed your ACHI controllers , trying finding the newer ones and or installing the previous one if. Usually windows update doesn't include the ACHI drivers for your motherboard so you would have to surf the web.

and do you have a printer installed (namely HP, because remembering back, those stupid printers hp gives would screw with me, with their drivers installed.

OK, thanks again.
I tried changing the USB setting, and installing the newest Intel 9.1.1.1015 I could find on Guru3D for the ACHI/chipset. But, no change.
What sort of energy report do you guys get? I mean, are these USB errors (in post #1) normal?

I think so, i checked mind for you and i got the usb suspended error. The energy report is supposed to help you use your power more wisely..based of this

How to Run an Energy Report on Windows 7 | eHow.com

so that might not help your problem.

OK guys, I've sussed it.
It was because W7 wasn't on the boot drive!
I dual boot with OSX86 and W7 from the OSX drive. Changing the boot drive to W7 sorted out the sleep issue. It occurred to me that this could be the problem as I couldn't get W7 to install unless it was to the boot drive, so I had to change the boot order for installation and then back again to get my dual boot working.
All I have to do now is decide whether I want dual boot or Windows sleep!
Does anyone know a workaround for this? Will EasyBCD work or will it screw up my Snow Leopard install?

Hi imacken

I knew that we must have something in common that was causing this and I knew that it wasn't just something in the release version of Windows 7. I had W7 sleeping fine right up until today when I finally got OSK and Ubuntu installed.

The thing is, I use GRUB2 (default with Ubuntu 9.10) and the only reason I didn't install it to the first partition (Windows 7 partition) is that I'd had all sorts of problems getting OSX to work and whenever I used something like Chameleon it messed up my Win7 loader and I had to launch the repair tools from the Win7 CD to get it fixed (several times this happened) so I thought I'd play safe and install GRUB2 to the 4th partition (Ubuntu ext4 partition) and make that active, then if it all went wrong I could just make Partition 1 active again and still have Windows 7 working.
Now of course as Partition 1 isn't active my sleep is broken!

To fix this then I could just trust GRUB2 and install it to Partition 1 and then Windows 7 should be happy enough to sleep. I can always recover using the repair tools again if i need to.

Maybe you can do something similar with a third party bootloader?
There is WinGRUB (GRUB4DOS and WINGRUB | Get GRUB4DOS and WINGRUB at SourceForge.net) but I couldn't work it out to be honest.

P.S. OT but How did you get Snow Leopard to install?
