Hi, Apparently this is a design flaw in that unit. I am including just one of many discussions and cussing about this unit. There is according to one poster a key combination that resets things for a time but Acer is not passing it to end users. Based on what I read if you can return the unit you might want to consider it. Good luck Ralph
