Power Manager Not Running

If the System Preference is showing a Power Manager not running message, your Mac probably needs to be restarted.

The Power Manager not running message appears when Power Manager's daemon is not available. This may be because the daemon has stopped running or the System Preference is unable to talk to it.

Restarting Power Manager's Daemon Manually

On Mac OS X 10.4 Power Manager's daemon is controlled by launchd. This excellent tool lets you start and stop daemons from the command line.

To start Power Manager's daemon use the following command in the Terminal utility.

sudo launchctl load /Library/LaunchDaemons/

To stop Power Manager's daemon use this slightly different command.

sudo launchctl unload /Library/LaunchDaemons/
