When the computer finishes its start-up procedure, you should see the Mac
OS desktop. If you see a blinking question mark, you need to install the
system software on your hard disk (though a problem with the hard drive
or a misconfigured SCSI chain can also cause a blinking question mark). See
Troubleshooting
on page 35 for details. If you see a blank screen or anything
not already described, see
Problems starting up
on page 11.
When you need to shut your computer down, follow the instructions in
Shutting down the computer
on page 13.
Problems starting up
If you see a blank screen when you start up, check the following items to
identify the source of the problem:
■
Are the computer and monitor plugged in? If they are plugged into a power
strip, is it plugged in and turned on?
■
Are the computer and monitor turned on? The power button on the front
of the computer should be lighted. Most monitors also have power lights
which should also be on.
■
Is the video cable securely connected to the monitor and computer? (If you
need to reattach the cable, first turn off the computer and monitor.)
■
Are the keyboard and mouse properly connected to the computer? (If you
need to reconnect them, first turn off the computer to avoid damage.)
■
Is the brightness control on the monitor turned too far down? Check the
documentation that came with your monitor for instructions.
■
If the image on the monitor has a green or purple cast, or the display
appears dark, then you may be using a monitor that requires support for
Sync on Green. Older Mac OS computers used a process known as Sync on
Green to produce proper video output. Most computers today do not
support these types of monitors and instead support a standard called
Composite Sync. You should consult with the manufacturer of your
monitor to determine which type of monitor you have. Adapters are
available from most monitor vendors that allow the use of older Sync on
Green monitors on your new Power Computing computer.
