Laptop Mbox strange noise

[Denkelag]

Hi.

Just installed Mbox on my laptop (Acer1350) works nice without the charger pluged in. When I do that a strang noise and disturbance appear from mbox. Does anyone have a clue to solve this??

Try a different (better) USB cable, and move the M-Box away from the lap-top / pwr supply.

I've found my usb cable on my M-box, capable of picking up RF

If the laptop charger has a grounded AC plug, you could try a ground lift adapter. If that cures the noise, its likely a ground loop.

I´ll try that.
