Display
Why did the computer screen (LCD) go blank?
❑The computer screen may go blank if the computer has lost power or has entered a power saving mode (Standby or Hibernate). If the computer is in LCD (Video) Standby mode, press any key to activate the computer screen. See Using the Power Saving Modes (page 90) for more information.
❑Make sure the computer is plugged into a power source and is on. The power indicator on the computer will be on if the computer is on.
❑If the computer is using battery power, make sure the battery is installed properly and is charged. See Using the Battery Pack (page 21) for more information.
❑If the display mode is set to external display, use the Fn+F7 key combination. See Combinations and Functions with the Fn Key (page 27) for more information.
What should I do if the screen does not display a video?
❑If the external display is selected for the output destination with the Fn+F7 keys and the external display is disconnected, you cannot display a video on your screen.
❑In such a case, stop video playback, press the Fn+F7 keys to change the output destination to your screen, and then restart video playback.
What should I do if the screen is dark?
Press the Fn+F6 keys to brighten the screen.
