My customer was attempting to use her latitude d600 to drive a external
projector for a seminar. Somehow she managed to lose video on both the
internal lcd and the external display. Upon booting you have video
until Windows XP
loads (and presumably the point where the video driver loads) then the
screen goes blank while the system continues to boot up. The Fn + F8
keys DO switch activity between the two monitors but there is no
display. Also, in safe mode it will boot just past MUP to AGP440.SYS
and there it hangs. Tried switching modes in BIOS but it's PW locked. The customer says she dissabled something in the monitor settings but can't remember what it was!!

check device manager to be sure your video card is functioning properly. If it looks good in device manager, shut off the pc, connect the external monitor/projector to the pc and start up the pc with the external device powered on. if no video from external device, then the video card/external connector is probably bad. Contact Dell if in warranty.
maybe the fn/f8 keys are not working. Can you get a safe mode boot prompt by repeatedly pressing the f8 key immediately following power up on the laptop? if no, f8 key is likely dead and you need a new keyboard. If f8 is okay, does the fn key work with other functions? if no, fn key is bad - new keyboard.
Hi there if you have plugged into your external vga port all you have to do is press fn + f8 that should now show the image on both laptop and external ie projector
