Troubleshoot AC Adapater
Unplug your Wii AC adapter from both the console and the power source.
Unplug everything from your Wii's USB and controller ports.
Keep everything unplugged for at least two full minutes.
While waiting, check the AC adapter for signs of damage. A cracked case or frayed wires means you should replace your adapter
Check your adapter for the word "Wii" and model number "RVL-002 (USA)." These are signs that your adapter is licensed and legitimate. Unlicensed adapters occasionally cause problems with the system.
After two minutes, plug your adapter back into the Wii. Plug the other end of the adapter to a wall outlet, not a power strip or surge protector. If your power light comes on and stays on, you've successfully fixed your problem.
If your problem hasn't been fixed, replace any unlicensed or damaged adapters and game accessories. Make sure your Wii is properly ventilated by standing it vertically and clearing dust from vents.
