    Workaround For "Unattended Wakeup" Sleep Timeout Bug Now Also Bugged


    There has been a bug in Windows sleep that has existed in both Windows 10 and in previous versions. When Windows wakes from sleep, on some machines it sees the wake event as a remote wakeup event. The result is that the normal power settings are completely ignored, and a specific registry settings overrides the sleep timer.


    This link describes the problem:


    https://answers.microsoft.com/en-us/windows/forum/windows_8-performance/windows-8-pro-goes-to-sleep-after-60-seconds-of/b1a32492-f9cc-4db9-ad70-987af074fa08?msgId=e37ac74a-6c29-4f1d-82af-ad837dadc371&tab=question&status=AllReplies&page=5


    Note that this link is from all the way back in 2012 under Windows 8. However, the same bug still exists in Windows 10. EVERY time Windows 10 has a major update, these registry settings are set back to the default of 120 seconds (2 minutes). The workaround is to use regedit to change the corresponding registry keys to some larger number.


    The registry keys are located at:


    Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\238C9FA8-0AAD-41ED-83F4-97BE242C8F20\7bc4a2f9-d8fc-4469-b07b-33eb785aaca0\DefaultPowerSchemeValues


    As of update 1809 for Windows 10, this workaround no longer works. After waking from sleep, at least one computer that I own goes to sleep after 2 minutes no matter what the power settings say. This registry setting no longer fixes it.


    My guess is that another registry setting needs to be edited. Anyone have an idea how Microsoft may have broken this again?

    :)

  2. unattended sleep timeout

    Hi,

    Thank you for posting your query in Microsoft Community.

    I will assist you with this.

    Specifies the duration of inactivity before the system automatically enters sleep after waking from sleep in an unattended state.

    For example, if the system wakes from sleep because of a timed event or a wake on LAN (WoL) event, the sleep unattended idle timeout value will be used instead of the

    sleep idle timeout
    value.

    Hope the information was helpful.

    Thank you.

  3. unattended sleep timeout

    I have a question Mr. Deepak. Why did MS remove the system unattended sleep timeout in Windows 10? Many users including myself are having issues where our PC's would go to sleep after only a few minutes. This after setting the sleep settings to much longer
    then that. In my case, after rebooting, the PC would go to sleep after 30 minutes which is what I specified. However, upon wakening the PC it would start to sleep after 3 minutes. This behavior could only be changed after a reboot and then the cycle above
    would repeat.

    This site provided the only solution to my problem. He provided a reg file to put back the unattended sleep timeout in the advanced power settings. Once there is showed 2 minutes timeout. I set it to match my regular power and sleep settings for 30 minutes.
    So something else is going very wrong with windows 10 to ignore the regular power and sleep setting and then to default to the unattended sleep timeout which is hidden and not even shown in the advanced power settings. So that is a setup for frustration.
    There is plenty of forums and users that are complaining about the issue. Other then this, my PC has no issues. Device manager is clean with no conflicts. No crashing, blue screens for over a month of use.

    Power Options - Add "System unattended sleep timeout" - Windows 7 Help Forums

    The above link is the only fix for users on the dreaded pc going to sleep every two minutes regardless of system sleep setting.
