Well, got my J3 back today, the power button has been reattached to the motherboard. But unfortunately, it is now not responding to button presses. The unit connects to PC and battery charges. I can power on the unit by connecting USB to wall outlet, but even then the power button does not respond (Can't power it back off or activate hold mode, etc.). All other buttons respond as normal. Guess it's back to RMA land!
