S7010 Freezes when I tap near the PCMCIA area...

I have a S7010 that has a freezing/restart issue when I tap the notebook anywhere near or directly on top of the PCMCIA area (the left palm rest). Sometimes, the degree of sensitivity differs- setting my palm over the area to type doesn't affect it, but tapping the area, pressing firmly, picking the notebook up, or tilting the notebook to its left side most likely causes it to freeze. Hitting other areas of the notebook doesn't cause the computer to freeze most of the time, but if I hit hard enough, it'll either reboot or freeze.

I disabled the PCMCIA from task manager, but that didn't do anything. There is no setting under BIOS that lets me disable PCMCIA. Since the freeze occurs whether I'm in BIOS, loading, or Windows, I don't think this is a software related problem anyway.

For the hardware troubleshooting...
I already disassembled the notebook and reassembled it several times to make sure parts weren't loose. I took advice from another thread and tried heat gunning the chips near the PCMCIA portion of the mobo (to get the soldering mixed again chemically), but that didn't help either.

After reading my attempt at troubleshooting, does anyone have any more workable suggestions? Should I just try baking the whole mobo?

 

The only thing I can think of is don't tap near the PCMCIA area...
