Thanks for quick replies.
I was hoping you would say what you did
The socket thingy could well have had a knock, I'm not to careful to be honest. The Tab goes in back pack for the motorbike (have a case for it), but the charger is left to fend for itself.
It was crammed into the bottom of my bag with portable HDDs and other cables etc, so could well have had a bump.
Will look to replace the socket thing and/or the cable if I have to.
