Answer to "My kindle won't turn on. Is it the battery?"My kindle has been in a drawer for a year because it wouldn't turn on despite all my reboot efforts. Seen this and thought before I tossed it to give it a try. Popped the back off with a razor knife, touch the metal connector piece like this says, plug it back in a boom starts i like a champ!! My 3rd Generation Kindle Fire went dead. Won't seem to charge or just has a black screen? I had two. Here's what I did. I carefully slipped a sharp knife in the slit where the case splits and took the back off. I then slipped the connector for the battery out of its receptacle. I slid the metal knife edge across the metal contacts on the battery plug and plugged it back in. My Kindles both immediately booted up and worked fine. Pretty sure this voids the warranty but at this point what matter does it make? This happened to both of mine exactly 30 days after the warranty ran out.
