Left this in storage fowr a few month's as I was quite happy with my old N73,the N96 was working fine before I put it away but went to plug it in to charge it onlt to find it's completly dead,no sign's of battery charge light's nothing,done the usual remove battery etc but it's not having it,not sure what else to do but to take it to a authorised repair centre,would it be a problem as I had bought it from ebay from a genuine seller?
