I have a Viewsonic 7 tablet less than a week old that just stopped running it's OS all together. I could not imagine why, but all that appears on the screen when I press the power button is the background image and the so-called "task-bar"on the top indicating the time and the fact that it is in flight mode. I can hold the power button in forever and not see any change. It will not longer comply...please HELP ! Now I am just waiting for the battery to die out so I can recharge them from point 0.0%...I am not counting on that as a solution tho...has anyone else had this problem occur?
