Solutions to common probl ems
The computer is turned on but the screen is dark.
One of the following is probably the cause:
mYou have a screen saver programthat 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.
mThe monitor’s brightness control (¤) is not adjusted properly.
Check the monitor’sbrightness control and turn it up if necessary.
mThe Macintosh or the monitor is not getting power.
Check that the monitor is plugged in and turned on, and that themonitor
cable is fi rmly connected to both the computer and the monitor.
Check that the computer’spower cord is firmly connected to the computer
and plugged into a groundedelectrical 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.
The computer’s clock keeps time inaccurately.
Your computer has a clock that runs continuously. When the computer is
turned off, a battery keeps the clock running. If your clock begins to keep
time inaccurately, have your Apple-authorized service provider replace the
battery.
