I was unpleasantly surprised last night when while playing with my Wii, my remote suddenly stopped working. I didn't drop it or hit it against anything or even lay it down for that matter. One second it was functioning normally and the next the remote's power was off. When I tried to turn it back on, the lights would blink several times and then it powered down again. The sytem would only power on and off if pressed the power button on the console. My first instinct was to change the batteries so I did (twice actually). I also tried resynchronizing the remote but of course that didn't work. Then I came to the conclusion that I was going to have to exchange it. I was also worried that the problem may have something to do with the Wireless Sensor Bar or even worse, the console. If that was the case, I would have to exchange the whole system. And if I needed to do that, I knew the chances of them actually having the Wii in stock was slim to none.
Fortunately, all that worry was for nothing as a couple of hours after the problem began I had an idea which I thought was a Hail Mary, but I decided to try it anyway. All I did was unplug the AC cord from the back of the console and plugged it back in. I honestly didn't think there was a chance it would work but I was willing to try anything. Imagine my surprise when I pressed the power button on the remote and everything was back to normal. Both the remote and the console powered up and I haven't had any problems since. So if you ever experience these same symptoms, try what I did before you start to worry. I hope it works for you too.
