Your mileage may vary given how much fun I had. The second registry location is referenced by: In Advanced settings expand Display > the Console lock display off time-out to set the values you want when on battery or plugged in. Once the registry is updated go to Control Panel > Hardware and Sound > Power Options > Edit Plan Settings and then change advanced power settings.

This will enable the Console lock display off timeout in the advanced power options. Set the data of the value “Attributes” to 2 There are two registry locations that enable the mystical “Console lock display off timeout” HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\238C9FA8-0AAD-41ED-83F4-97BE242C8F20\7bc4a2f9-d8fc-4469-b07b-33eb785aaca0

However, on my Windows 10 install there appears to be more than one key detailing the change! There are numerous forum posts about setting the registry entry to enable it.

The magic setting that worked for me was “Console lock display off timeout” which seems to be carried over from Windows 8/8.1 but oddly remains hidden from view in the advanced power settings in Windows 10. Lots of advice is given without explanation unfortunately and this makes comparing situations hard. There are unfortunately a lot of very similar issues surrounding this and other issues to do with power saving, lock screens and the screen saver which made searching for the right answer very tricky. Mine did, and it was really irrationally irritating!

Does your Windows 10 machine power off the screen after 1 minute on the lock screen, leaving you with a black screen after just 1 minute?
