You can also use the Monacor FGA-40 filter, which lifts ground, has two cinch connectors on either side and costs just 17.20 EUR. It is available in car audio shops or online for example here: http://www.power-discounter.de/p3721.html (Germany) > or > > b ) find another way to remove your laptop from ground. using batteries > is one, but then your processor slips into a lower mode and you lose > some of that computing power you paid for. a friend suggested using a > powerstrip that either has no ground or has had its ground removed. > haven't tried it yet, but that sounds like the best bet. Well, epanorama calls this solution the "cheater plug" and doesn't recommend it: http://www.epanorama.net/documents/groundloop/problem_solving.html > better than hacking the grounds off your AC adaptor, at least... :-) The result is the same as the ground-less plug and thus might be dangerous, as well. ciao -- Frank Barknecht _ ______footils.org__
