Plug [Q] Tablet not charging after update.

I updated the tablet yesterday using the Sony PC companion and after the upgrade it will no longer charge. I tried 3 different cables, 2 different PCs and every usb port on them. I tried 3 different wall chargers including the original sony one. I tried it in safe mode and also turning it off and plugging in the cable. It will not connect to my pc and I am really annoyed that the tablet will not charge. It is now dead so I am not able to access it any more.
