Apple Power Macintosh 5400 series - Manual (Page 40)

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. (The
power switch is near the location where the power cord plugs into the back of
your computer.) Use this method only if you cannot choose Shut Down or
Restart following the instructions in “Using the Power Key” or “Using the
Shut Down Command.”
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 the computer on after you’ve shut it down with either the menu
command or the keyboard:
m
Press the Power key (marked with the 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.)
