If you have a problem with your monitors staying on for hours after you lock your pc, this fix is for you.
Since you’re using Windows 10 and want to adjust the lock screen timeout via the Registry Editor (`regedit`), I’ll guide you step-by-step to the exact location and explain what to do. This tweak will allow the “Console lock display off timeout” option to appear in your power settings, which controls how long the lock screen stays on before powering off.
Steps to Adjust Lock Screen Timeout in Registry Editor
Open Registry Editor:
Press `Win + R` to open the Run dialog.
Type `regedit` and press Enter. If prompted by User Account Control (UAC), click “Yes” to proceed.
Navigate to the Correct Key:
In the Registry Editor, use the left-hand tree or copy-paste the following path into the address bar at the top:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\7516b95f-f776-4464-8c53-06167f40cc99\8EC4B3A5-6868-48c2-BE75-4F3044BE88A7
Press Enter to jump directly to this location.
Modify the Attributes Value:
In the right-hand pane, you’ll see a few entries. Look for one named `Attributes` (it’s a DWORD value).
Double-click `Attributes` to edit it.
Change the “Value data” from `1` (default) to `2`. This unlocks the timeout setting in the Power Options menu.
Click “OK” to save the change.
Close Registry Editor:
Once you’ve made the change, close the Registry Editor. No restart is required yet.
Adjust the Timeout in Power Options:
Open the Control Panel: Press `Win + S`, type “Control Panel,” and hit Enter.
Go to *Hardware and Sound > Power Options*.
Next to your active power plan (e.g., “Balanced”), click “Change plan settings.”
Click “Change advanced power settings” at the bottom.
In the new window, scroll down to the “Display” section and expand it.
Look for “Console lock display off timeout” (it should now be visible thanks to the registry tweak).
Set the time (in minutes) to your desired value (e.g., `1` for 1 minute).
Click “Apply” and then “OK.”
Test the Change:
Lock your screen (press `Win + L`) and wait to see if it powers off after the set time.
Notes:
If “Console lock display off timeout” doesn’t appear after editing the registry, restart your PC and check again.
Be careful in the Registry Editor—only modify the specified value to avoid unintended changes.
