Explain me about sleep states

[x509]

I've been tearing my hair out (what's left of it ) with a sleep/hiberation issue on my ASUS X79-chipset motherboard. I keep reading about how lots of guys have this issue and about different sleep states.

I thought that there was just "sleep" and "hibernate." No?

Sleep and hibernate are controlled by your OS, one saves the current session to memory, the other saves it to disk. Sleep states are controlled in your BIOS and determines how much of your system goes into a low power state or even off after a period of inactivity. The last BIOS update on my sig rig (which is similar to yours) had an additional option under C states (sleep states). I OC so I shut off these options in BIOS and OS.

Thanks. I'm having problems with my system going into hibernation, and then "popping back" into an active state. So should I turn off all these various C states in BIOS? Am I correct in guessing that my problem is BIOS-based and not OS-based?

I've been working on sleep issues lately just something to troubleshoot. This issue is possibly hardware related. For example, on win 8.1 xbox 360 controller will cause problems with "away mode". Do you use ai suite?

A bios setting is probably not what's causing your computer to wake its self up. Check your event viewer to see if anything there is concurrent with the computer waking up, also check scheduled tasks. You can disable the ability of some devices to wake your computer, such as not allowing your NIC/Lan/Wan to wake the system.

As Bluesun311 alluded to AI Suite can cause a multitude of issues, Bluetooth connectivity comes to mind.

Here's a good little guide to find out what is waking your computer: http://www.howtogeek.com/131464/how-to-see-which-app-is-blocking-your-pc-from-going-into-sleep-mode/

I personally have all C-states enabled and every other power saving option enabled in BIOS and after days of troubleshooting finally have sleep working in Windows 8.1 x64.

There are definitely some quirks that can keep your computer from sleeping which are hardly obvious in a lot of cases. In advanced power options for your current power profile, in the "Multimedia Settings" category, make sure "When sharing media" is set to "Allow the computer to sleep". Also, ensure your network card is set to wake on lan by magic packet only, or disabled completely if you don't use WOL.

Powercfg -requests showed nothing hardware related keeping my computer awake and putting it to sleep manually worked fine, it stayed asleep. So, I set the sleep timeout to 1 minute and just started killing processes one by one and letting the computer idle for a minute after each one. 2 hours and 40 processes later I still couldn't get it to sleep on it's own. In my case, I had to leave my current homegroup and disable the homegroup services. Seemingly unrelated and very obscure, this was the end solution for me. Ridiculous but it worked. I prefer to use old school passworded shares anyway, so dropping the homegroup was not a big deal.

Guys,

I really, really appreciate these suggestions. About a month ago I posted a question in this area to the ASUS X79 chipset thread and RAJA (very helpful guy!) suggested that I do a clean install. In my case, I did the Win 7 install for an older Intel chipset board. I did a motherboard swap without incident, except that the sleep/hibernate modes which worked fine with the older board are now giving me grief. Raja suggested a clean install, as a point of departure for experiments. Well, I need to find the time to put in a spare drive to do that clean install, but now for the first time I have almost a checklist of things to look for.

Much, much appreciated, guys.

One thing I just realized is that logitech setpoint software was causing insta-wake issues for me on w8.1. Installed it for the drivers, then disabled the setpoint program from loading at startup.

Edit: nevermind, needs to be uninstalled completely, I think.
