It is not altogether clear to me whether the entire key mechanism is
missing (broken off or unsoldered from the board) or whether it is only
the key cap. If the latter, there is a good chance that the key cap
acted as a retainer for the retract spring that keeps the switch from
closing with out finger pressure. If this is the case, you might use a
straight pin or equivalent to make sure that the plunger part of the
mechanism is help in the retracted position. Then power up, and note
the results.

If it is the `totally gone' problem, I'd harken to Tony's remarks!
