my mp4 player was workin fine, then i pluged it in go my cpu w/ the usb cable to charge, & it did charge, but when i unplug it its dead, nothing happens. i can plug it back in, still shows a full charge, & it will play music & vids, etc only while pluged in, i can even have it on & playin music while pluged in & if i unplug it while playin music it shuts off. i even left it to charge over night w/ same results. its fairly new & barley used, & i havent messed w/ the firmware or anything.
