Follow this guide to get to the disc drive Nintendo Wii DVD Drive Replacement From there you will have to open the drive, you should be able to find a video for that on youtube. If you have experience in this kind of work, feel free to do it yourself. But if you do not then I recommend that you take it to a repair shop that specializes in game console repair.

I do not know of any other way to shut off the phone, best thing I know to do is run an app or video that will cause excessive battery drain. Sorry, but I'm almost positive that there's no other way.
