Amazon Fire Tablet,a surprise gift to me from Mrs P has developed a fault.The charging cable is loose when inserted into the port.So you can put it on ,go back and it has slipped loose while you were away and has not charged and has even lost more battery power.Google, problem and it is well known,one online solution a large rubber band,wrap it around the top of the cable pull down tight after inserting cable and fasten off,guess what it is working.Google is your friend.
