 Is the power cord securely plugged into the back of your Mac Pro?
 If you have connected a keyboard and display, are the keyboard and display cables
connected correctly?
 If you have connected a display, are the brightness and contrast of the display
adjusted correctly? If the display has brightness controls, adjust them. If the display
has a power button, make sure the display is turned on.
 If you have connected a display and you don’t see anything on your screen, restart
your Mac Pro. Hold down the power button (®) on your Mac Pro for 5 or 6 seconds,
until it turns off. Press the power button (®) again to restart.
 If you see a blinking question mark on the screen or a series of flashes from the status
light, see Chapter 4, “Problem, Meet Solution” on page 75.
