The same thing happened to my iPod Nano 6th generation. I had a warranty on it through Best Buy, and now they don't sell that model anymore. Everything else on the iPod works amazing, but it ***** that I can't use it as a watch or even to work out (because I can't "wake it up" to change songs). I checked around the web, and it seems that this Power/Sleep/Wake button has gotten stuck for a whole lot of other people. See here:

So if this problem is a manufacturer default and not something that I did, then I think there should have been a recall. But I understand if there weren't enough people "reporting" the problem, then it didn't warrant one. However, why should I have to pay $75 + shipping to Apple for them to fix a manufacturer's hardware defect? If I had the teenie tiny tools and the know-how, I would fix that little piece that came unattached to the bigger piece within the internal mechanisms and underneath the Sleep/Wake button, myself. But I'm not so inclined. I noticed at https://ipodrefresh.com/iPod-nano-6th-gen-Power/Sleep-Button-Repair.html that it is actually not that big a deal to fix, that is, if you know what you're doing and have the correct part.
Can anyone at all help me with this? Why is Apple charging so much to fix their own mistake? If after sending it to them, they say that it was my fault, then I will gladly pay, but I rarely used it outside of the car. -- Jordy
