How to Change System Unattended Sleep Timeout in Windows 10
The System unattended sleep timeout power setting is the idle timeout before the system returns to a low power sleep state after waking unattended.
Adjusting the system unattended sleep timeout period can be handy if you had created a task in Task Scheduler to wake up the PC to run something. You could set this timeout to be long enough for the task to have time to finish running before Windows goes back to sleep automatically.
This tutorial will show you how to change the system unattended sleep timeout for how many minutes you want before automatically going back to sleep or hibernation in Windows 10.
If the PC wakes up from sleep or hibernate mode and is used by you (no longer idle) during this system unattended sleep timeout period, then Windows will no longer automatically go back to sleep after this timeout period. Instead it will use the time period you set in your Power Plan Settings for Sleep or Hibernation.
- Option One: To Change System Unattended Sleep Timeout in Advanced Power Plan Settings
- Option Two: To Change System Unattended Sleep Timeout in Command Prompt
The System unattended sleep timeout setting is not shown in Power Options by default.
If you haven't already, an administrator will need to first add "System unattended sleep timeout" to Power Options to be able to do this option.
1. Open the advanced power settings for your current chosen power plan.
2. Expand open the Sleep setting, set the System unattended sleep timeout settings to how many minutes you want, and click/tap on OK. (see screenshot below)
The default time is 2 Minutes.
3. When finished, you can close Power Options if you like.
1. Open a command prompt.
2. Enter the command(s) below you want to use into the command prompt, and press Enter. (see screenshots below)
(On battery)
powercfg /SETDCVALUEINDEX SCHEME_CURRENT 238C9FA8-0AAD-41ED-83F4-97BE242C8F20 7bc4a2f9-d8fc-4469-b07b-33eb785aaca0 <seconds>
AND/OR
(Plugged in)
powercfg /SETACVALUEINDEX SCHEME_CURRENT 238C9FA8-0AAD-41ED-83F4-97BE242C8F20 7bc4a2f9-d8fc-4469-b07b-33eb785aaca0 <seconds>
Substitute <seconds> in the commands above with how many seconds you want for the time.
The amount of seconds you enter will show rounded up or down to the nearest minute in Power Options.
The default time is 120 seconds (2 minutes).
3. When finished, you can close the command prompt if you like.
That's it,
Shawn
