The device will continue to operate off of external power from your computer, but the battery charge level will not increase. If this is the case, the device may display a red battery icon, which is normal.

While plugged into the computer, if you allow the device to count down to 0, the device will enter file transfer mode and enable communication with your computer. This will be indicated by an image of a GPS and computer connected on the screen. When on this screen, the device will receive a very slow charge from the computer.
