Win7 will not sleep RRS feed

  • Question

  • I am in a 2003 forest functional level AD domain and am troubleshooting users whose PC's will not go to sleep. I have power plan set via GPO, I verified these users/computers ARE getting the policy and the policy is applying. However at the prescribed time, the PC attempts to go to sleep, however does not. Instead locks the session (not hang, just like CTRL+ALT+DEL / lock). I verified PC's can go into sleep mode if user chooses start/sleep without issue.

    I am wondering what logging is available for me to troubleshoot this. I believe this is related to some update, patch or software installed domain wide because it is happening to a significant number of people. PC's are all Win7 Pro or Enterprise.

    Thanks in advance.

    Platform Timer Resolution:Platform Timer Resolution
    The default platform timer resolution is 15.6ms (15625000ns) and should be used whenever the system is idle. If the timer resolution is increased, processor power management technologies may not be effective. The timer resolution may be increased due to multimedia playback or graphical animations.

    Platform Power Management Capabilities:Supported Sleep States
    Sleep states allow the computer to enter low-power modes after a period of inactivity. The S3 sleep state is the default sleep state for Windows platforms. The S3 sleep state consumes only enough power to preserve memory contents and allow the computer to resume working quickly. Very few platforms support the S1 or S2 Sleep states.

    S2 Sleep Supported false
    S3 Sleep Supported true

  • Run powercfg -devicequery wake_armed to see which devices can resume your Windows.

  • I have done everything on that KB article already without effect.

     

    Ironically I did try this and it worked. Changed all sleep settings to 1 minute, and it works fine. anything longer than 10 minutes DOES NOT work.

  • Have you tried other values (15/20 minutes)? Does this work?

  • No, it does not work reliably for anybody. I have 3 boxes, it works on none of them. I have 1 user it does work consistently on. I find no differences in the PC other than model. I have updated all drivers and bios and sleep settings are set by the same GPO for all users. I find it puzzling that there is no way to verbosely log this issue like you can for other windows issues.
