Typically that's the over voltage protection kicking in, specifically
to avoid the nasty brown smells. :-) Bear in mind I haven't touched
a switch mode internals for 10+ years, so the state of the art may
have changed some since then. FWIW, my two IBM laptop brickettes
do spit out a voltage under no load.
