I am not knowledgeable on PSUs, what does this mean?
Thanks

Socket was wet and shorted out maybe? You need a decent amp draw (dead
short) to kick a breaker. Shorting a capacitor would let out smoke and the connection after it melted away.
I just lost a power cord to my mutli voltage laptop brick, the brick is
fine
but the power cable shorted out at the 3 prong plug
(smelly).
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?
Regards
Rob
