Wii U Error Code: 160-0101

I was just wondering about the following error code I have suddenly received on my Wii U Gamepad & TV display:

The exact steps of what was going on with the system prior to the error was as follows:

1. I was playing through a lengthy session of Zen Pinball 2 on my Gamepad (my main TV screen was off at the time).
2. I was done playing for the night, so I quit my current table & returned to the main table selection screen of the game.
3. I then pressed the Home Button on the Gamepad in order to close the game & return to the Wii U main menu
4. The Wii U Home Menu appeared on screen & I then pressed the Close Software icon.
5. The screen above appeared on the Gamepad screen. Upon turning on my TV to the proper input, I noticed this Error message was also being displayed there as well.

I then attempted to look up the error code on the Nintendo Support page for the Wii U in an attempt to figure out what was the issue, but upon entering the code I received the following message:

After that, the only thing I could do was to attempt to turn off the console as instructed by the error code. I first attempting to do so the standard way by holding the power button on the Gamepad until it powered off... unfortunately, this did not power down the main console as well. I pressed the power button on the Gamepad once again, and it powered up to the same error message being displayed. I then attempted a shut down by holding the actual console's power button for 3 seconds. This time the console itself powered off & the Gamepad displayed an error that it had lost communication with the main system. Upon powering down the Gamepad, I was able to boot the console back on via the Gamepad & was taking to the main prompt screen to choose a profile.

I don't know how common this error is, but couldn't find anything useful on the internet & felt that at least documenting it could at least be a start for someone else who might come across this same Error Code.
