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 point what matter does it make? This happened to both of mine exactly 30 days after the warranty ran out. This worked on my wife's new Kindle also.
