We have an Iconia tab a500 and the power adaptor no longer connects. It feels as if something is loose I'm the socket when trying to connect the cable. It is definitely out of warranty, but I don't want to just throw it away. Does anyone know how we can send it in for repairs? We had to send it in when we first got it because of a broken power switch and were very happy with the service, but now I can't talk to anyone to even try to pay for repairs.
