Interesting as I had the same thing happen when I used one of their adaptors on my A3000. Unfortunately, not only did it not work, but now when I plug in the OLD working original adaptor my 3000 will not boot with that one either.
Dead in the water and I don't know why. (And yes it worked just fine until I tried the adaptor.)
So not sure if the adaptor was the issue or the power supply I tried but one of the 2 appears to have blown my 3000 and I am quite sad...
