  1. 1

    Hit any key on your keyboard. This will bring the laptop out of hibernation and light the monitor if it is in the Sleep mode.

  2. 2

    Press the "FN" and "F10" keys on your keyboard simultaneously. Press several times to see if the screen comes back.

  3. 3

    Hold down the "FN" key on your keyboard. Press "F6" to increase the brightness of the display. It is possible the brightness level is not adequate for the lighting conditions. Pressing "F7" while holding the "FN" key down will lower the level.

  4. 4

    Replace the monitor if there are large bright or dark spots on the display. This would indicate the monitor is faulty.

  5. 5

    Reboot the laptop. The system will run a test of the monitor as part of the normal booting sequence. If the POST test detects a failure in the operation, your laptop will need professional service. Contact the support representative from Fujitsu.

  6. 6

    Connect an external monitor to the laptop. With the laptop display facing you, locate the external VGA video port of the left side of the computer. Attach the VGA cable from the external monitor to this port. Push the connector from the monitor into the port on the laptop until it is seated then tighten the screws on each side of the connector. Hold down the "FN" key on your keyboard and press the "F10" key until the external monitor displays an image. If the external monitor works with the laptop, the internal LCD display is faulty.
