My son let his battery completely drain. when he tried to charge it, nothing happened. Did not get the red battery icon or nothing indicating it was charging.
I took his battery out and put it back in...still nothing. Then I put it in my Pre and immediately got the battery icon. I recall reading the forums a long time ago where people warned of letting the battery drain all the way. Can someone shed some light on this issue? One thing I did not try was to keep his plugged in longer to see if it would eventually start charging.

Thanks a lot & have a great day.
