I have had my tablet for a month with no problems. I have the power block and original cord, along with a backup OEM power block and cord. Both cords and power blocks have been working without a hitch since i purchased this. Today for no reason i can figure out my Tablet decided to quit charging. I do not get any indication that the cords are even connected to the tablet. i have tried both cord setups on several different outlets that i know have power. without any luck. I have completed both a soft and hard reset. also without any luck. I currently have 5% battery life left on the tablet. I found this forum by researching this problem and decided to join. This comment i think deserves to be repeated I AM ONLY USING THE OEM POWER BLOCK AND CORD. so please do not ask me if i am. Thank you for your help.
