How to enable and configure Power Management in Configuration Manager 2012.
Start off with creating a new custom client device setting.
Select only Power Mangement and check the enable box.
Now I like to create a custom folder and device collection to better control where I deploy the custom client settings.
You might want to create a separate laptop collection and a desktop collection.
In my lab I only have laptops so I only have one collection.
I would recommend to add an exclude rule to exclude all %server% ?
Now right click the new collection and choose properties.
Click the Power Management tab.
Here you may copy an existing power management plan from another collection or create your own.
Create one for peak hours and one for non-peak hours.
Click the View… button to get/set all the details.
Finally you’ll have to deploy your custom client device settings to the new collection.
