The lamp turns on and off on it's own and the touch dim, on and off don't work when this occurs. It's not the power outlet as I have something else plugged in with no disruption. This started about 3 months after purchasing so I was not too concerned as it was only happening once in a whole. It will be a year that I'VE had it now it's happening most of the time. It's unfortunate because it had all the features I needed.
