Does anyone know how to get a Samsung galaxy note 10.1 GT-8000 to startup. I bought this product recently on EBay. I've recharged it already, but because it is second hand I don't know when the battery was last fully recharged. Because it is secondhand, the previous owner said it doesn't work and took it to have it repaired .But it still doesn't work.Does anyone know how long it takes to fully recharge a Samsung galaxy battery, if it's completely flat. If the battery does work, what else could stop it working
