This has happened for the second time within a week. The battery gauge of my Reader 650 is down by one bar when I stop reading a book. I make sure it's turned off. The next day I am trying to turn it on again - but the scree remains blank. Nothing works, not even a reset. I plug into a USB port. The red charging light illuminates. After a while the device comes back to life, reboots and shows the charging symbol. The battery was completely discharged!
Does anyone else have similar problems with the battery charge suddenly dropping from three bars to zero overnight?
