Apple Power Macintosh 4400 - Manual (Page 112)

4 If your computer still doesn’t restart, turn it off by pressing the power button (
I
) on the
front of the computer. Wait at least 30 seconds, then turn the computer on again by
pressing the Power key (marked with a
π
) on the keyboard.
If you suspect that the problem is with other equipment, such as a printer or
an external hard disk that’s attached to your computer, turn that equipment off
for 30 seconds or longer. Then turn it on again and restart the Macintosh.
Rebuild your desktop
A process known as “rebuilding the desktop” helps your Macintosh keep
track of data on your startup disks. It’s a good idea to rebuild your desktop
once a month or so.
Rebuilding your desktop can solve a number of problems. For example, when
application documents are no longer represented by application-specific icons
(and are instead represented by generic icons on the desktop), rebuilding the
desktop fixes the problem. Afterward, appropriate icons should appear for
all documents.
Some extensions may interfere with rebuilding your desktop. To prevent
problems, you’ll need to turn off all extensions except Macintosh Easy Open
before you rebuild your desktop. When you finish rebuilding the desktop, turn
the extensions you normally use back on.
