Apple Macintosh LC 580 - Manual (Page 50)

4 If the power switch doesn’t turn off the computer, unplug your Macintosh.
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 10 seconds or longer, then turn it on again and restart the Macintosh.
Rebuild your desktop regularly
A process known as “rebuilding the desktop” helps your Macintosh keep
track of data on your startup disks. Although you usually use the hard disk in
your computer as a startup disk, you can also start up from any other disk that
has system software installed. It’s a good idea to rebuild the desktop of your
startup disks once a month or so.
To rebuild the desktop of a startup disk, follow these steps:
1 Hold down the Option and
x
keys while you start up your computer.
Do not release the keys until you see a message asking whether you want to
rebuild the desktop.
2 Click OK.
