Using Powercfg to Change the Active Power Scheme (last updated October 31, 2016)

For this tip we want to change the active power scheme. First, we'll get a list of the available power schemes (covered under another tip). (See Figure 1.) Figure 1. Powercfg -list.

As you can see, there's an asterisk on the right of the Balanced line, denoting that it's currently the active scheme. Let's say that we instead want the High performance scheme to be active. You do this by specifying the "-SETACTIVE" (or "-S") switch followed by the GUID of the scheme you want to be active: (See Figure 2.) Figure 2. Powercfg -setactive.

Now the asterisk is beside the High performance scheme, denoting it's now the active one. This tip (13491) applies to Windows 7, 8, and 10.

My primary use for Powercfg is to turn off hibernation and remove hiberfil.sys. From an admin command prompt, enter:

powercfg /h off

Hibernation is a function whose time has passed, and hiberfil.sys is a big waste of space on a small SSD in a laptop.
