Start with a an aircraft in a cold and dark setting, then load the L-1011, and after it is loaded turn the Battery Switch OFF.  It's found on the Second Officer's Lower Panel, down near the bottom right of the Electrical section.

Once you have turned the Battery Switch OFF, you can save the flight, and then load that saved flight, and the Battery Switch will be OFF. You can then move the L-1011 to the location of your choice, and it will still be OFF.
