gmkarthikeyhan 2 Report post Posted January 9, 2011 Does Mp3 player work without battery when it is inserted to a USB port? ie. I am having a mp3 player of Yes.. www.iloveyes.net 2 days before it turned off indicating Low Battery Warning. I usually charge it by means of USB port in the system. when I connect to port it shows a charging symbol and the system detects as a removable media. but it is dead now is it problem of battery or else in player, I removed the battery it is li-polymer 3.7V 280mAh 3mm thichness battery. but even though the player has problem in battery it should work as removable device when it connected to system. But one of my friend said that Mp3 player of my type only get power from battery even when it connected with USB port is it true. Guys pls find a solution will it work if I change the battery.
