/LIST, /L Lists the names of existing power schemes. You can see the same list in the Power
Schemes tab of the Power Options Properties dialog box accessible through the Power Options
applet of the Control Panel. This command line switch varies from the /Query command line
switch that you can use to see the actual power scheme settings. You can use this command line
switch to obtain a list of Globally Unique Identifiers (GUIDs) for the various power configurations
as shown in Figure 12.7. Simply type PowerCfg /L and press Enter to obtain the information.
The GUIDs are important in performing other power configuration tasks. Notice that the
output places an asterisk (*) next to the currently selected power scheme.
