I have had a Sony Ericsson W705 for about three months now and it suddenly wont charge anymore, its says that I need to have a Sony Ericsson battery even though it is, it's the one it came with. Now its dead and I cant use it at all!
www.sonyericsson.com is no help at all!
And I can not find anything about this problem anywhere!

Ok... Person who answered first, I ordered it online... And I don't have any like reciepts and the return date is way passed... So...
