I'm having a problem like this, but different. I was modifying the memory on my HP Pavilion ZT1185 but I forgot that it was still plugged in (The battery is dead, so I threw it out a long time ago). My screwdriver slipped and hit 2 soldering points and the whole thing sparked for a split second before I removed it. I re-built it to see if it still worked. The results:
Fan starts spinning for 4-5 seconds, then stops and the computer never boots. I'm pretty sure it's the CPU that was shorted, but I'm not sure. At least I think I shorted something. For all I know, I could have fried the MB.
