Windows 11 Idle Screen Timeout setting not working

Question

Good afternoon, I have a windows domain with a GPO setup to lock all computers after 10 minutes of idle activity. The policy had been working fine, until just a few days ago. I have looked at the local machines (Windows 11 Pro) under gpedit.msc and the policy is still correctly set, however, the machine no longer sleeps after 10 minutes of no activity.

Is there any way to monitor if something is actively keeping the machine awake, or an event log that shows idle time?

Thank you

Answer 1

I shall suggest you update the graphic card driver first. Download and install the latest driver from the support site of the manufacturer. Once done recheck the issue.

Hello there,

You can use told like procmon to check what is interfering with the GPO.

You can Enable 'Audit logon events' policy and then calculate the idle time. Navigate to Computer Configuration> Windows Settings>Security settings>Advanced Audit Policy Configuration>Audit Policies>logon/logoff.

Under that, turn on auditing for 'Audit logoff', 'Audit logon' and 'Audit special logon' and enable it for both 'Success' and 'Failure'.

Look for event IDs 4624 (Account was logged on), 4634 (Account was logged off), 4647 (user initiated logoff) and 4672 (special logon), 4800 (the workstation was locked), 4801 (workstation was unlocked).

These logs show the amount of time a user have spent working on their workstation. The rest of the time can be considered as an idle time.

Did you ever figure this out? I am starting to notice the same behavior.

Sadly no. My admin has made an extra GPO group for windows 11 computers where the standby timeout is disabled.
Manually set on every PC to 10 Minutes works as a workaround.
