Serial5 - cannot power down

[Kishen Gopinath]

I held down the little button for 10 seconds per instructions - the green led tunrs off, I release , and a couple of seconds later , the blue led blinks and the green led comes  back on again

Pretty misleading - how can I power this thing off ?

I had the same problem today. I disconnected my AirCable and took it with me to lunch. Whne I was far enough away from my pc, the blue light went off and I was then able to hold the button down for 10 seconds and it powered off.
