Push sleep immediately again, PC goes to sleep, and 1 out of every 3 or 4 times actually goes into true sleep with fans OFF--the way it should. The other times it goes into this kind of half sleep with the fans ON, but all indicator lights on the PC show its asleep. I use the PC for a while interactively, push sleep, PC goes to sleep but fans remain on in that kind of half sleep. It just doesn't like it when I wake it up.
It's really a strange behavior. Did you try a Clean Boot? Disable non-Microsoft services then check if it works. Does this issue occur after you built this new PC? Is this image installed on another PC? Are there something special in your image? It seems really difficult to find the cause of this inconsistant problem.
I susgest you contact Sandy Bridge to check this chips, it seems they have the utility to visual presents the fans speed, temperature and etc. There's nothing I can research anymore on my side, unfortunately.

It ended up being because I added my network printer to the printers folder by clicking 'add a network printer' rather than 'add a local printer'. When I added a 'local' printer and pointed it to the IP Address of the printer the sleep issue went away. Weird, right? Just to add on to your info Kramy.
And thanks for connecting the link to the network printer. That was driving me nuts! I had the same problem with the network printer causing the fans not to turn off in sleep mode. You can correct this though. In your power config advanced settings, under sleep, make sure "Enable Hybrid Sleep" is turned on. If the option is not present then at a CMD prompt run as administrator type "powercfg -h on" to enable hibernation. Then you should be able to use hybrid sleep.
On my computer I was now able to have the network printer device installed and have a complete sleep mode. For me it even helped to turn off the printer before entering sleep mode - as an interim solution. For some motherboards, no solutions will work. My motherboard only supports S1. The fans are always on. Thanks again as your fix worked for me too. Homebuilt MSI mb, win8. Start an elevated command prompt.

In reply to jstewar9's post on January 31, Disable the devices on the motherboard. Machine is perfect except for it! I searched for a few hours looking to resolve it and came across this post on the forum and the registry edit here completely solved the sleep issue on my machine and I haven't had any issue with it since! I did try this, and it seems to work in a fashion, but the only way to wake up now is a long press of the power button.
A short press as with my HP laptop seems to wake something up, but the display remains blank. With all my previous laptops HPx3, Toshiba A long press on the power button is usually associated with a forced power down.
It is not enough to support S3. Of course, going Linux is an alternative. Dell presumably don't like the burden of supporting two sleep modes, for both of which bugs do get reported, and are difficult to diagnose.
