Some items of note:

I had been using Badass Battery Monitor for 2 weeks before the failure. Could that have affected it?

At 15% the Fire always issued a signal to recharge. This time it died with 19% still left in the battery.

I had gone thourgh 8 full charge cycles before the failure.

Screen Wake Time was at 4 hours before the failure acording to Badass Battery Monitor. That seems low when the projected life was supposed to be 7 hours.

When connecting the power cord for recharging, the Start Light always turned on. This time it did not turn on.

I connected the Fire to my PC and it did not open as usual. I had thought, even if the battery was dead, I'd be able to look at it's hard disk via a USB connection to my PC.

I had gone through the last cycle only using Sleep Mode. In the past I had always used Shut Down Mode every night. Could a whole cycle of only Sleep Mode damage the battery?
