Mac OS X 10.3: Retaining Energy Saver schedule preferences

Mac OS X 10.3's Energy Saver preferences allows you to schedule a time for your computer to automatically start up (turn on) and shut down. However, if you click the preference window's lock icon to lock the settings (this prevents further access without a password) right after you make changes, your schedule settings won't be remembered.

Don't worry; you have a couple workarounds:

• After editing your Energy Saver schedule, open any other preference (either by clicking Show All or by choosing one from the View menu) to save the settings. Then, if you wish to lock your settings, go back into Energy Saver preferences and lock (de-authenticate) the preference.
  
  
• Or, just quit System Preferences after making your scheduling changes, without clicking the lock icon, and your settings will be saved. After that, if you wish, you can go back into Energy Saver preferences and lock (de-authenticate) the preference.

Note: The preference will be automatically unlocked the next time an administrator logs in.
