I had a 500 back charge once when it was connected to a laptop to charge and the laptop went to sleep. There was nothing wrong with the laptop, the 500, or the cable. It was because of the laptop going to sleep.
[quite]No, that is to enable devices to be charged or keep running when the laptop is sleeping.[/quote]
It also prevents back charging. Maybe newer devices have circuitry to prevent back charging. I don't know as I've never looked into it.
