Hi all I have a z5 which decided to be fussy and won't let me charge it using all my regular wall chargers. Before I send it to Sony for repair I am charging it using my Panasonic hifi system which has an ipad USB port on it. This charges the phone everytime! Mine is model sc-hc38db. Just thought it might help those of you who desperately need to charge your phone or need to retrieve your stuff from it. Sony support have no solutions for me, mine won't connect to pc and safe mode restart won't work either. I will be sending mine off shortly but for now this solution is making do.
