Last night our Wii wouldn't turn on. It had no power. But since my friend had a similar issue a few months ago, I already knew how to fix it. Should yours ever not power on, you need to reset your power cord. To do this, you need to unplug it out of the wall and out of the Wii and leave it unplugged for at least 2 minutes. After that, ours powered right back up!
