There were a number of 286 versions. They are all called "Model X", for instance I've got a Model 60 which is one of the 286 models.

The PS/2 PSUs were like IBM stuff in general well built and I believe contained various protective circuitry to shut them down to prevent further damage, which may be what is happening here. I wouldn't be entirely surprised if this is just a loose connection due to the move causing the PSU to not detect something properly. As such the magic of taking something to bits and putting it back together without doing anything else may work as all the connectors will be reseated.
