Usually they only fail if overheated, sometimes they do delaminate and get
noisy but that's harmless other than being annoying.

    ... It's true that a cheap TRANSFORMER power supply designed for 60Hz may well overheat on 50Hz. ... However, all laptop power supplies are "switching" power supplies, which are incredibly indifferent to the AC line frequency, since the very first thing that they do is full-wave rectify it and minimally filter it to DC, without a transformer or any ... A cheap powersupply designed for 60Hz will more than likely overheat and fail on 50Hz (if you don't believe me, buy a cheap one from R'shack and try, or just buy an electric toothbrush not specified for 60Hz and try it in Europe. ...
