I was using my father's computer while mine was in the shop, and thought I would clean out under the keyboard to be nice. Unfortunately, I managed to break his D key in the process.
Needless to say, he's very unhappy about it.
I'm not quite sure what the issue is - the "rubber spring" or cup is still there, but even when pressing on it with my finger, it does not register the key press. The only thing I can think of is that the rubber cup is not connected to the plastic layer underneath as it is with the other keys.
Any help would seriously be appreciated. I would prefer not to have to spend money on such an old machine.
