Thanks everyone. I'm waiting for the "Sources" store to open to try the GL Isolater per Mac. My hardware Guy says that 2 prong would be OK but keep an eye. I have till 5:00pm today with Futureshop to return the laptop after putting it thru it's paces for 14 days. Just by accident discovered the noise dilemma yesterday. Might MSI work with me in some fashion as I got the
laptop specifically to have on stage. They offer 2yr warranty in Canada, 3 yr in USA. The unit more
compact than other 16" and 1/2 lb. lighter. So I am dispointed to say the least.
