Solutions to common problems
This section contains descriptions of problems you could
experience with your computer. Some problems may be caused by
your CD-ROM drive, so if you do not find your problem here, be
sure to check the section Solutions to CD-ROM problems on page
6-23.
The computer is powered on, but the screen is dark.
One of the following is probably the cause:
• The computer or the monitor is not getting power.
If you have a separate monitor, check that the monitor is
plugged in and powered on and that the monitor cable is
firmly connected to both the computer and monitor.
Check that 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 Mac OS Guide, available in the Guide (
T
) menu.
• You have a screen saver program that darkens the screen
when the computer has not been used for a certain period of
time.
Press a key or move the mouse to turn off the screen saver.
• Your computer has been put in sleep mode.
Press any key to wake it up.
• The monitor’s brightness control is not adjusted properly.
Check the monitor’s brightness control and turn it up if necessary.
