One question that occurs to me; how do we know that when we put the
chip in it won't be immediately cooked again because the fault is
actually somewhere else? Do we have enough information to verify that
the chip is the only problem - it seems kind of unlikely it'd
spontaenously fail without receiving some sort of nasty jolt.
