Topic: I disconnected the wii u from the power supply

Hey everyone!
First of all, sorry if my English is not the best, but I need some help... I'm really afraid...
I had a problem with my Wii u Console.
When I turned on my GamePad, the Wii u Console didn't recognize the Wii u GamePad, so I turned off my GamePad but the Console didn't turn off...
Because of that, I tried to click on the power button of the console but it doesn't help and the console didn't turn off so I disconnected the Wii u from the power supply.
After that everything worked good but I'm afraid that I destroyed something because of what I did and my questions are:
1. If everything works good, can I just leave it and continue with playing or should I need to be aware to the console because what I did even if now everything works good?

2. The Wii u built for such things? I mean if there is a problem that requires you to disconnect the Wii u from the power supply?

Big tnx and sorry if my English was bad ><

I've had to do that a number of times when it has frozen and even holding down the power button on the console didn't shut it off. It will be fine.

I've switched it off from the power supply several times because my Wii U had frozen or something had gone wrong, and it's fine. You might lose some save data for a game but that's it, just don't do it all of the time
