Dell monitors automatically go into power-save mode after a preset amount of time when the computer is inactive. The Dell monitor will go completely black, instead of showing a screensaver. This doesn't mean that your Dell computer has shut down. Instead, this allows your monitor to essentially turn off until it's needed again. You can change how long it is before the Dell monitor goes into power-save mode by changing your display settings.

• • 1 Press any key on your keyboard or move your mouse. Either will turn off power-save mode. Alternately, you can press the power button on your Dell computer tower or laptop.
    
    
    
  • 2 Press any key a second time if the monitor goes from power-save to stand-by mode. Stand-by mode allows the screensaver to appear.
    
    
    
  • 3 Enter your user name and password into the login prompt if your computer requires a login. Press "Enter" to begin using your Dell computer.

Click the "Screensaver" tab and press "ower." Beside "Turn off Monitor," choose a time amount from the drop-down list and press "Apply."
