This happened to me (er, my RT) a few months ago.

I'm afraid that the only wire you should jiggle is the phone cord to
contact IBM repair...  When it happened to me, I tried all sorts of
variants (swapping CPU boards, removing AFPA, etc.) without effect.
IBM simply came in, swapped the planar (system) board, and I was up
and running again in 15 minutes.  It's times like this that I am
glad I bought a service contract...
