    What is the operating system?

    Does it start in Safe Mode or Last Known Good Configuration (if applicable)?

    This may not help, but it's something that has happened to me.

    When you use the Fn F8, keep these things in mind:

    1. Hold Fn, Tap F8 once, let go of Fn
    2. Wait 5 seconds
    3. Go back to step 1 and repeat if no change

    You may have to do the above process a few times.

    I found that I was doing it too fast due to my impatience. Although it may not solve your problem, maybe it'll eliminate the issue of being assigned to the wrong output/monitor.

    You can try Fn F5 also. There should be a image of a monitor in blue on the particular key. If you can see the Bios Screen and then nothing when it boots into the OS, then it is a driver issue. If you cannot see anything on the screen, but can on an external monitor hooked up to the VGA port, then the LCD cable or screen could be the culprit.

    Was this monitor ever working OK?

    If it was, try Last Known Good Configuration. (same menu as Safe Mode etc)

    If not, try updating your video card/chip drivers.

    Does anything show up on the screen as the computer boots??
    If nothing shows there may be a physical error with the screen. It may just be broken.

    Try pressing the reset button on the bottom of the unit. If the LCD does not light up or no display, the cable could be damaged between the base and screen. Time to send it in for repair.
