I bought the NWZ-W273 yesterday and what the guy told me was to leave it for 2 hours to charge I have done that but the battery has not charged I restared the walkman and the software and did all of the above again. but only difference this time is that a voice comes up on the mp3 then a beep then the green flashing light goes straight to flashing red. The cradle's red light does not stay lit for long either. I am thinking brandnew bit of kit should not do this??? Anyone else had similar problems to mine
