What happens if you use an extension lead from another power supply for the
lap top and a seperate one for the Hi Fi ?

Hello there folks,

I am trying to sort out a buzzing problem I have when connecting my
laptop
to my hifi.

If I plug the laptop into Mains (AC power), then into my HiFi which is
also
plugged into Mains, there is a buzz problem.

If I plug the laptop into Mains but listen on headphones (using the same
minijack output socket), there is no problem

If I use battery power on the laptop and connect it to my HiFi, there is
no
problem...

SO there is only a problem when BOTH laptop AND HiFi are connected to
the
Mains.

Anyone have any ideas what to do to fix it, or where the problem comes
from?

Your input would me MASSIVELY appreciated!

Thanks,
Mark.
