Apple Macintosh Performa 6400 Series - Manual (Page 22)

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 standby power button (®) on the back of
the computer.
IMPORTANT You could lose unsaved work if you use the standby power
button on the back of the computer to turn it off. Only use the standby
power button 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 π ) on the keyboard.
Note: Your monitor may have to be turned on separately each time you turn
on the computer. If you have trouble turning on your computer, see the
section “Problems Turning On Your Computer?” earlier in this chapter.
