Your friend probably broke it, obviously. In which case you can't return it. You should post the topic http://www.wiichat.com/nintendo-wii-hardware/ if you want a real answer.
All the buttons on the remote work fine, the pointing also works fine however no motion is detected, this is my second remote so I do know how to sync n stuff so its not that because my other remote works fine, I received the remote with WiiPlay before I had my console and lent to my mate.
All I want to know is has this happened to anyone? And can it be fixed? And if not whom do I need to contact to get a new one as I have hardly used it at all I really do not want to pay for a new one myself...
