I am sorry to say the power receptacle/jack which receives the charge from the power cord has become loose or dislodged.
The Jack needs to be replaced to get everything back to alright.
The only option left is to send it for repair, for that you have to send it to Amazon because amazon directly supports and services the Kindle. You'll need to call them, and obtain an RA# ***** to sending it. In some cases, Amazon will not repair the Kindle and instead will offer a refurbished one at a lesser cost.
Here is the link for Kindle Service and Warranty information along with their phone number.
You can also contact kindle support at
United States: 1-***-***-****
Outside the United States: 1-***-***-****
Sorry to give you a bad news.
