Apple Macintosh LC 630 DOS - Manual (Page 91)

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.
Solutions to common problems
The computer is turned on but the screen is dark.
One of the following is probably the cause:
m You have a screen saver program that darkens the screen when the
computer has not been used for a certain period.
Press a key or move the mouse to turn off the screen saver.
m The monitor’s brightness control (¤) is not adjusted properly.
Check the monitor’s brightness control and turn it up if necessary.
m The Macintosh or the monitor is not getting power.
Make sure the monitor is plugged in and turned on, and that the monitor
cable is firmly connected to both the computer and the monitor.
Make sure the computer’s power cord is firmly connected to the computer
and plugged into a grounded electrical outlet, and that the outlet has power.
If you have more than one monitor and only one is dark, check that it is set
up correctly in the Monitors control panel. For information on using more
than one monitor, see the “Monitors” topic of Macintosh Guide, available
in the Guide (h) menu.
