Non unibody MBP shuts off when shocked with static electricity

So, just as the title states, my non-unibody MBP shuts off when I shock it with a static shock. It's not my fault really, as the air here is really dry (although I've resorted to touching something metal near me before touching the computer, and that works fine). I have the computer plugged in the the grounded extension cord thing, so why is this a problem? I know that static shock is horrible for electronics, but shouldn't this be taken care of somehow?

I just want to make sure nothing is wrong cause my 3 year applecare is about to expire.

Thanks in advance.

Oh and no, this has never happened to me before, just twice today. It'll shut off completely. It did once while the computer was asleep, and once while it was awake.

No ideas? And yes, that's me selflessly bumping my own thread...

Thanks guys, I'll call them up right now. The thing is, the computer isn't shocking ME, I'm shocking it, then it turns off. I'll let you know the results.
