What part did I destroy?

While replacing the LCD on my MBP, I made the mistake of using metal tweezers to disconnect the battery. I shorted two pins out, I saw a spark, and now the laptop is dead. Not even the MagSafe connector lights up. Can someone help me ID the part I fried so I can replace it without having to buy multiple parts and do a trial-and -error process? Here is a photo of the pins I shorted out.

OK, you have screwed the pooch.

Go to the top Mac board level repair guy in the world (don't tell him I said so, his head is big enough), Be willing to pay New York City prices and see if he is willing to attempt it. His name is Louis Rossman. a distinct PITA, but the best at something like this. Google him to get an idea of what I am talking about.

Whole Logic Board replacement would be needed. If you shorted out soldering points on the MLB, it probably shorted out most of the board. Hard to tell where the current slowed down and stopped or the path it took.
