Seriously. Wtf! My m90 started humming while plugged in but powered OFF! What the hell is going on!? Help!!!
Whoa never thought of that. I usually keep two or three plugged in. As soon as I get home I'm unplugging them. Thanks for that tipReli said:I have several that do that. So, I never leave any plugged in anymore. It wastes power.....they aren't energy-star certified or anything
