There is something that worries me both
in my new MAG DJ530 15" screen and 6-7 years
old IBM PS/2 model 90. They both produce
a very quiet and very high-pitched sound when plugged
into the wall socket (and not on!), and
if I unplug them there is sometimes a small spark
between the plug and the socket. Why does this
happen and what could I do about it?
