Oh No. I'm Sorry. Mine is kinda dead right now (battery) so it sits (but still works). On two occasions in it's history it acted like you describe. Each time I had to plug it in to the wall charger directly and let it charge for several hours and then do a rest. Each time I did this process several times and it finally came back.
The final issue I had with mine before I stopped using it was that it would forget all it's bookmarks every time I connected to the computer/calibre. I never did figure out why it was doing that or why it started. It worked fine for years and then just went insane.
