  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.
  
  Best Regards
  Dale

  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.
  
  Best Regards

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

  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
  S4 Sleep Supported	true

  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.
  
  Best Regards
  Dale

  Hi,
  
  In Group Policy I enable Turn Off the Hard Disk and now the computers going to sleep. It is OK. Thanks a lot.
