Perhaps it's only an issue with > units made in the past two or three years.. I've got a year old DELL Inspiron 8100 laptop that I've been happy with. I couldn't recall having any noise problems, so I decided to check it out. I'm using the audio on the mother board, hooked up to a Mackie 1402 (using one of the stereo channels, w/input gain set for -10db devices), hooked up to some cheap powered speakers. Under normal listening conditions I hear no noise (re-charger connected or not). I also don't hear any noise under normal conditions using headphones connected to the headphone out on the mixer. If I turn off the music, and crank up the volume of the headphone output on the mixer, I do get some definite electronic noise that goes away when I disconnect the re-charger. Clearly your mileage varies. -daveh -------------- Dave Hastings dhastings@earthlink.net "Outside of a dog, books are a man's best friend. Inside of a dog it's too dark to read" Groucho Marx
