  • Hi,

    By analyzing the energy efficiency report, I noticed that the disk idle is disabled by Group Policy on your computer. Have you configured any Group Policy setting to disable the hard disk going to sleep? Moreover, the CPU Utilization seems to be high because of updates of Antimalware. This let me suspect that whether the antimalware blocks this group policy to be enforced on your computer. I recommend you to temporarily disable the antimalware and see if the sleep goes well.

  • Hi,

    Please confirm if the System Sleep Timeout is enforced by Group Policy, you can view the setting in the Power Options Control Panel. If the policy is enforced, you'll notice that a message in the yellow banner indicates that some power settings are enforced by the system administrator. Note also that the Put the computer to sleep selector used to change the System Sleep timeout setting is disabled. If it is the case, please restart the computer in clean boot to identify if the issue is caused by third party program. BTW, please help collecting power energy effiency report and posting in this forum.

  • Hi,
    The Group Policy is enforced, user doesn´t change settings. If i tried switch computer to Sleep mode manually it work ok. But when the time expired computer stay power on, sleep mode not work correctly via GP.
    There are install standard programs, e.g. Office 2007, Adobe Reader 9, Windows  Live Messenger, K-Lite Codecs.

  • I performed the test and made it work till I restarted the computer. So have you restarted your computer after the Group Policy was enforced.

  • How about configuring in Power Option panel to set the time for sleep instead of enforcing by Group Policy? Does it work? Moreover, try using the following command to test:

    Powercfg -Change -standby-timeout-ac 30

    Meanwhile, could you please help to collect powercfg energy report? This may help us identify the issue.

  • Hi,
    It doesn´t work, if I set the time in Power Option.
    There is powercfg energy report:
