Changing Overlay power Mode with script

Question

Hi,

I want to change the overlay power mode based on time of the day without having to go to settings -> system -> power and battery -> power mode each time.

I am not able to find which command in powercfg will change the OVERLAY power mode, all the commands seem to be applicable only to the control panel power scheme settings.

I am looking for a command that I can run from cmd or powershell to set the power mode: Balanced, Best Performance, or Best Power Efficiency and then call it from a scheduled task.

Can anyone help with this?

Thanks

Hi, @Mustaffa Abu-Sedira !

Windows stores the overlay power mode setting in the registry under:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\User\PowerSchemes

The available Overlay Power Modes correspond to these registry values:

Power Mode	Registry Value
Best Power Efficiency	1
Balanced	2
Best Performance	3

You can Run PowerShell as Administrator and use one of the command:

Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\Power\User\PowerSchemes" -Name "ActiveOverlayAcPowerScheme" -Value 1

After setting the registry value, apply the new setting by running:

powercfg -update

You can schedule these commands to run at specific times of the day using Task Scheduler.
