    Dell Latitude D520, Model Number PP17L. At present, the hard disk is blank and I am working strictly in the BIOS.

    When I got this laptop, I was told its screen didn't work and the user had been using an external monitor for several months. It took me quite some aggravation to realize I had to have its lid fully closed in order to activate the external monitor.

    Here are the things I would like to know about:

    1) Is there a way to activate the external monitor with the lid open so I can use the laptop's keyboard? At present, the external monitor goes blank instantly on lifting the laptop's screen/lid.

    The only settings I can find in the BIOS concerning video are:
    • Brightness on Battery
    • Brightness on AC
    • LCD Expansion
    LCD Expansion has to do with whether the image is displayed with a wide black border or the image is edge-to-edge.

    There are no other menu items in the BIOS that could even be remotely interpreted as affecting video.

    2) The laptop's LCD panel does flash something for about a quarter of a second on the screen during POST when the external monitor is not connected. My guess is the LCD's power inverter is bad. What other possibilities are there?

    There should be a Key combo for switching to external...I think it is <FN-F8>


    Have you tried tapping F8 immediately on startup for safe mode

    Not much you can do in Bios.....having a OS on the HD would help
