Hi, you wanted a reply on why the gamepad went from not able to turn on Wii U to working fine.
Well I had noticed after leaving the battery out for an hour, than my fully functional gamepad stopped turning off the Wii U.
Though turning on the Wii U manually would turn on the gamepad as well.
I figured it would not hurt to resync the gamepad to the Wii U again, so I did, and found that resyncing corrected the power on issue from the gamepad.
It was a simple no brainer to me.
