I was loading music to my mp3 sansa after i was done i disconnect the wire from my mp3 all the sudden my mp3 screen saying disconnected and don't kno how to take it off the screen or try to fix it

Well try it charging if does not then connect it with you computer or laptop and if computer does recieve the noticfication that mp3 player is connected then remove it safely do not disconnet wire from the player but first from computer or laptop then try it if gets on.... if doesn't without connected to computer the reconnect with computer and format your player by right clicking on the mp3 drive and chosing format button . Let me tell that there is not much possibilty that it would be working again usually Directly disconnecting gives the memory **** to mp3 player as its not furter connected to stable power supply which would explain that it won't be working or any repaires would help then
