I also have had this problem, I charge it overnight and in the morning it is completely discharged and showing the battery thing. The battery is NOT bad, there's just no charge in it because the Kindle does something weird. I have fixed it in the past by using other chargers and after a bit cycling the power a couple of times. It eventually starts working again, you just have to out stubborn it. This is probably the fifth time I have had it do this.
