I read about this solution and I also asked Acer, if they could provide a 2-prong plugged cable for their laptops. They wrote me, that in Germany they are not allowed to supply such a cable for their laptops, but I could try to find one somewhere else... I guess, that the case of a laptop is well isolated from its innards, and also a lot of cases are plastic, so it seems. But if it's not isolated, the user would be the ground connection chosen, and that'll hurt. ;) Then the epanorama docs say "Do not do this", because it's "potentially very dangerous": http://www.epanorama.net/documents/groundloop/problem_solving.html They call the plug-solution a "cheater plug": http://www.epanorama.net/documents/groundloop/cheater.gif ciao -- Frank Barknecht _ ______footils.org__
