Apple Macintosh Performa 5400 Series - Manual (Page 19)

If you can’t shut down your computer
If a problem with the computer prevents you from using the Power key on
the keyboard or choosing Shut Down—for example, if the computer “freezes”
so that the pointer does not respond to the mouse—you can turn off the
computer by pressing the power switch on the back of the computer. Use
this method only if you cannot choose Shut Down or press the Power
key following the instructions in the previous section, “Turning the
Computer Off.”
IMPORTANT You could lose unsaved work if you use the power switch on the
back of the computer to turn off your computer. Only use the power switch
when there is a problem that prevents the computer from being turned off
with the Power key on the keyboard or the Shut Down command. To make
sure your work is saved, use the Power key on the keyboard or the Shut
Down command.
Turning the computer on
To turn on the computer after you’ve shut it down (using either the Power key
on the keyboard or the Shut Down command):
m
Press the Power key (marked with a triangle) on the keyboard.
Leave the power switch on the back of your computer in the “on” position.
(The side of the switch marked with the i symbol should be pressed in.)
