PowerCFG is a command-line utility that first appeared on Windows XP that gives advanced users access to all configurable power system settings, including many options you won't find in the Control Panel or Settings.

Each command has a unique syntax (sometimes called parameters or switches) to define options. Some of the available commands have a single letter shortcut when you see a forward slash with a single letter.

In some cases, you'll need more information about the possible syntaxes. In this situation, type in the command to see the available parameters. We've provided the basic syntaxes to get you started.

Finally, you might be told you can't run commands from the current location. As seen in the screenshot below, you can bypass this problem by using .\ before the command name.
