Thanks for your response.
"Electronics repair" is not my forte, unfortunately.
I don't think there is anything wrong with the connectors -
I've had other Thinkpads in the past with faulty connectors -
I suspect in the computer rather than the charger - 
and found this problem surprisingly difficult to solve.

I've just been clearing out old computers,
and found 6 faulty Thinkpads, mostly T23's or other T2?'s.
I've 6 working Thinkpads left, one T23, two T43's,
T60, T61 and T520.
I'm surprised how well the T23 works, under XP and Fedora-11.
I'm confirmed in my disbelief that computers are getting
better and better ...
