System shuts down while in sleep mode

Hi guys,
I built a Core i7 3770k, AsRock OC Formula, 650 watt PSU running Windows 8 64-bit computer last month. It has had some minor problems, as with any new build, but I fixed them with some simple adjustments.

Now (within the last week or so), it seems like at random, the computer will shut off while it is in sleep mode. The power button on the case stops lighting up, and when you turn the computer back on, it will whir up for about 2 seconds, shut completely off for 2 seconds, turn back on, and hang at the AsRock BIOS screen (press F2 to.....). Post on the MB stops at "IDE device detected". No HDD activity, nothing; although everything seems to be powered on fine. At this point, I press the power button once and the machine shuts off instantly. I press it again, and the machine boots up as normal, no hangs or errors whatsoever.

This seems to happen within a random time period (sometimes 3 seconds, sometimes 2 minutes) every time I put the computer into sleep mode, and regardless of whether an iphone or other usb device is plugged in or charging. If I shut down all the way, I have no problems at all. But I want to use sleep mode!

If anyone has any suggestions or solutions, I would like to hear them.

  1. Firstly enter BIOS and set your hard drive to run in AHCI mode . Also enable SMART monitoring . If you have an SSD disable hibernate too

    Then head for control panel and power options

    How are your power options configured?
  2. Update: from the time of my first post to now, my system was successfully in sleep mode. I had no USB devices plugged into it. It seems that when I charge my iphone or ipad during sleep mode, the problem occurs more frequently. The MB is designed to be able to handle charging during sleep.

    All drives are in ACHI mode with SMART enabled. OS is on bootable kingston ssd. Did not see settings for disabling hibernation on it.

    Power options:
    Put computer to sleep: Never
    USB selective suspend setting: enabled
    power button action: sleep
    sleep button : sleep
    system cooling policy: active
    Everything else set for max. performance.

    Should mention that I just installed a blu-ray burner. Also has an IDE DVDRW burner with an IDE to SATA adapter. They all work without a hitch. No video cards. Using integrated graphics.

    Also, only one stick of ddr3 RAM 8GB 400mhz (not the most familiar with RAM, but you get the gist I hope?)
  3. I cant remember if I had the problem before I installed the bluray, but would there be any way it would cause that much of a problem as to ruin sleep mode? It works perfectly; I have watched movies and burned with it a few times without any problem.
  4. According to , I shouldn't be coming anywhere near the capacity of my PSU, even when overclocked.
  5. If anyone is interested, I have changed all of my sleep button settings to hibernate just now. I will see if the computer works as it should. This is not a solution, as waking from hibernate is much slower, and I can't charge my phone that way, but all I can do for now. I have tried just about everything.
  6. try resting things so the power button is an on/off switch

    also let the power saving system sent the pc sleep after a reasonable time of not being used

    I think you should try that and see if it makes a difference

    And it will make manually putting it to sleep a little tedious with mouse but that would be better than what you have now
  7. Sorry, no difference at all with any of those settings. Its so strange. Everything else on the computer works without a hitch but sleep mode.

  9. Sooooo. I found an annoying little workaround that tells me this is not a hardware problem, but some kind of secret, nearly impossible to find software bug.

    Spent a whole day on the phone with Microsoft. The first guy I talked to changed nearly every setting on the computer around; the problem remained. The second guy took the easy way out and merely reinstalled Windows 8 over my old installation, making me have to reinstall all of my programs as well. This didn't work either. Stay away from Microsoft support if you know computers.

    My workaround:
    After googling for "sleep mode software" or something like that (looking for a different way to sleep, other than the S1 or S3 states - couldn't find anything),I stumbled upon a program called "Passmark Sleeper". It is a sleep mode testing program. And although my BIOS won't allow me to switch between standby states, this program allows me to "test" S1, S2, S3, or S4 states. I simply choose the S3 option and the "sleep forever" modifier (this program normally only tests each mode for 30 seconds), and voila! Sleep mode works again! I had my computer asleep for nearly 8 hours, and it woke flawlessly! Too bad I have to use a third party app to get it to work.....

    Anyone have any idea what kind of bug might be causing this now that we know its not some hardware problem? I still want to get to the bottom of this mess.
  10. Passmark Sleeper stopped doing the trick. I reinstalled Windows 8, no fix. Updated drivers, no fix. My problem may be my power surge protector. I have plugged the computer directly into the wall and have not had a problem yet, although I have not had the computer in sleep mode for long periods. I will keep you updated.

    I don't know if i am having the same issue as you or not. Occasionally when my computer goes to "sleep" even though i have sleep set to never and monitor to turn off after 15 mins. If i move my mouse, press a key on my keyboard, or hit the power button the monitor will not come back on but the lights on the front of my case that indicate power etc are all still on. Is this the same as what you're having issues with?
  12. Hi there. I am having the exact same issue as described in your OP. Same sequence of events when trying to turn it back on after it just turns off when in sleep mode. Did you ever end up solving this issue, or determining the cause? Can you point me in the right direction?
