Troubleshooting sleep issues

You can create an event log filter to show sleep and wake events: Sleep history: [Event sources = Kernel-Power, Power-Troubleshooting] and [Event IDS = 1,42]

If you want to see more power events, just remove the “1,42”

Connected Standby

Maybe it looks like it's going to sleep, but the event logs say it's not? Maybe it's going into “connected standby”, which you'll see in the event logs as:

Log Name:      System
Source:        Microsoft-Windows-Kernel-Power
Event ID:      506
Task Category: (157)
Level:         Information
Keywords:      (4)
User:          SYSTEM
Computer:      ADMIN-NOTE01.atcna.local
Description:
The system is entering connected standby 

Reason: Idle Timeout.

Windows 8 has redefined what we computer users think of as "standby." Now, if the screen turns off it is actually a form of standby. I believe it is called “connected standby.” Therefore, if the option to require password on wakeup is set it also locks when the screen simply turns off.

However, for domain connected computers you can set the following group policy to stop this behavior. It is the policy that controls the above listed registry key: [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\System]
“AllowDomainDelayLock”=dword:00000001

The policy is under [Computer\Administrative Templates\System\Logon] - Allow users to select when a password is required when resuming from connected standby - Enabled.

My current setting for Surface Pro's, we'll see if this works:

  • [Computer\Policies\Administrative Templates\System\Logon] - Allow users to select when a password is required when resuming from connected standby - Enabled.
  • [Computer\Preferences\Control Panel Settings\Power Options\Power Plan] - When plugged in, Turn off display after = 0
