Nook HD tablet won't charge
My nook HD tablet ran out of battery, when I try to charge it nothing comes on. The charge light flashes green then orange then after about 30 seconds flashes red! Ocasionally the nook start up screen will flash on for less than a second then it goes off again! I've tried holding down the power and nook button as I've read that resets it but still nothing! Any help or do you think its broke?
