Hello all I recently purchased a used MBA on ebay. I received the item with a power cord ordered since the item didn't come with one. Anyway it was working well and everything was fine until a week ago. For some reason it will not charge. I have tried different outlets and it just won't charge all of a sudden. The MBA works just fine it turns on and functions normally it just won't charge. The battery is indicating it needs service or replacement which I would agree with assuming it's the stock battery that came with the device but will that solve the issue? Should I return it? I have researched this topic on Google and none of the solutions work I have tried warming up the power brick etc NOTHING. ANY HELP IS APPRECIATED.
