I've had the iClever BK20 keyboard for just over 30 days (33 to be precise) and it suddenly has stopped working.  None of the blue lights above the numpad light up at all and two of the devices I've paired with it don't see it as "on".  I thought at first it was a charge issue, so I plugged it in to the charge.  When I do, the led turns red, and then it eventually turned green, so I thought it was good to go.  But still, when I unplug the charge cord and turn the keyboard on, I still don't see any blue lights, and my paired devices don't see it either.  What happened to this thing?  Has it died already??
