OK I had exactly the same problem for the past 2 days. Cleaned out my power plugs, changed my charger and no luck. Then I remember that I didn't reset the charge on the motherboard that builds up over time. To do this you simply turn off your tablet, then hold your power button for 4 to 5 seconds and it will double blink. POW! the device started charging again. Let us know if this works for you. Some devices require you to hold the power button for longer than 10-15 seconds before it works (Whilst off and nothing connected).
