AC adapter needs to be reset
Power issues can sometimes be caused by an AC adapter that needs to be reset. Unplug the adapter from both the console and the wall outlet. Wait a few seconds and reconnect both.
Faulty wall outlet
A bad wall outlet could be the cause for a Wii U not turning on. Test the outlet by plugging in another electronic device to ensure that the outlet is supplying power.
Broken AC adapter
The Wii U may not turn on if the AC adapter isn’t functioning properly. You can try a friend’s AC adapter or use a voltmeter to ensure the AC adapter is outputting the correct voltage.
If the console is overheating, the fan may be dirty and needs to be cleaned. It is also possible that the fan is not working properly and needs to be replaced.
If none of the above steps got your Wii U to turn on, most likely there is something wrong with the motherboard. Replacing the motherboard should finally get your unit to turn on.
