It is unlikely that there was anything wet, but I suppose I can't exclude
it. I am not sure what to do now.
I don't know the condition of the power cord now, I am not sure whether to
try using it on something else to see if it is OK, my multimeter shows no
shorts and no breaks in the wires so perhaps it is still good.
Also I don't know why the socket shorted, if it *was* wet then perhaps I
could plug it in again, but I am very doubtful that this would be a good
idea. Should I just be thinking of replacing the socket?
