Need Help?
If you don’t see anything on your screen or you think your computer did not start up
properly, check these items:
• Is the computer plugged into a power source? If it is plugged into a power strip, is
the power strip turned on?
• Is the power cord securely plugged into the back of the computer?
• Are the keyboard and display cables connected correctly?
• Is the display turned on? Are the brightness and contrast controls on the display
adjusted correctly? If your display has brightness and contrast controls, adjust them.
• Restart your computer. Press and hold the computer’s power button for
approximately 5 seconds until the computer turns off. Press it again to turn the
computer on.
• If you see a blinking question mark on the screen or see a series of flashes from the
status light when you turn on the computer, see Chapter 4, “Troubleshooting,” on
page 69.
