Ok the light is amber right now. When I do the 30-40 second press the screen does flash blank screen then just goes back to the tree. I am going to leave the case cover open and keep charging it until it turns green then try the power button and see what happens. It almost seems like the screen light only turns on when it's showing green but drains whatever it's building up but I'll keep checking on that.
Thank you for that battery link! I found a new one at newpower99 for $30 but if there's a chance I'm going to need to replace the device I like the used price of a hopefully easy fix much better.
I did plug it in to my laptop Saturday and it did show up (IIRC it just said Amazon kindle) but there wasn't really much I could do or see when I clicked on it. Was just kinda grayed out but I can check on that again as well.
Thanks much! You've given me some new things to try
