Apple PowerBook (Duo, 2300 Series) - Manual (Page 30)

When you choose Restart, the computer prompts you to save your work,
closes all open programs, and restarts itself.
Restarting using either of the methods outlined above does not affect your
RAM disk (if you created one) or its contents.
Trouble? If a problem with the computer prevents you from using the Power
key or choosing Restart—for example, if the computer “freezes” so that the
pointer does not respond to the trackpad—you can turn off the computer by
pressing the reset button (marked with a I) on the back of the computer. Use
this method only if you cannot choose Shut Down or Restart from the dialog
box that appears when you press the Power key, or if you cannot choose either
command from the Special menu.
