Inspiron 2650 Problem

OK,
The Laptop is a P4 1.6 40GHDD 512 ram fdd, cd/rw dvd.
It was operating fine. I transported it (safely.... no drops etc...)
Pulled it out and it wouldnt boot. No backlight, no monitor. I pulled the battery and after several cycles of on and off I got the blue Dell screen where it hung. After another few on/off cycles XP started to boot, while booting I popped the battery back in and it hung. The blue windows loading bar froze. I shut it down and since then it wont boot at all. No error beeps unless I pull the 512 card from under the KB. I have tried both of my HDDs, to no avail. I have tried booting with and without the CPU, HDD, CD/DVD, FDD, KB, RAM, my right index finger in my left ear while waving a flag with my left hand, and all possible variations thereof.
The power light does come on, the HDD spins, the cd will make detection noises when a disc is inserted, the CPU fan cycles, but no dice. I tried an external monitor, no green dot, only orange. If this was a desktop I wouldn't be posting, I would just start w/the vid card and move on down the line to the MB, HOWEVER my expertise in laptopland is limited. ANy ideas out there? My thought is a new MB, but I would lose my mind if I replaced it and found out I could have moved a jumper and then restarted.
Any help is appreciated.
