mitchiemasha Posted August 27, 2009 Share Posted August 27, 2009 Ive recently replaced my toshiba laptops power supply from a 3pin cloverleaf plug type, to a fig of 8 2 pin powersupply also 19v 5a. The annoying background noise has gone away.I guess 0v dv on the psu was grounded to the earth pin, causing the interference problem, which isnt just a hum loop type buzz, but cured by earth lifting.Has anyone done a sound comparison on Interspace I2s pc headphone balance box, compared to a usb, and 2x di boxes? I'm still unable to post freely on this site over this earth lifting lark on laptops. I bought a ground loop isolator of ebay for a few quid and it solved the earth hum problem.
