Late reply, but did you see this post a few topics down from yours?
That’s me. Same situation.
You have a dead battery and the only solution is to open up the Clip+ and replace it. There are tutorials and videos on how to do it; it helps to search and read/view all of them to get the Big Picture on how it all works.
Or you can order a new battery off eBay (there’s one for 17 bucks that’s supposedly OEM for the Clip+) and try your friendly local PC/phone repair shop to see if they’ll solder it in for you.
Or you can sell it and buy a working Clip+, which is what I did.
