Lisa- I connected an external monitor, and still no display. The laptop was originally dead. Ruled out the power connections, so replaced the motherboard. This is when it powered up, but did the seven beeps. The rewarming technique didn't work, so I then replaced the CPU. It now seems like it might be booting up, but no display.
Accessless-I remember connecting these connections, but I may have to go back and see if the larger display ribbon is still in place.
Geek- I will begin to go through the Dell pages.
Thanks for the help, any other ideas, let me know.
