I have 30 chromeboxes deployed in various locations and i have had 3 that have had the same problem. It appears the chromebox restored to factory by itself. They are unmanaged and the first screen that appears is where it finds mouse and keyboard. I dont know why this is happening but there were power outages on 2 of the 3 locations that this happened but there are 3 other boxes on those locations that are working correctly after the incidents. Does anybody know why this happens? To correct this i have to do a complete restore but since these boxes are deployed on other cities is very difficult to travel just to fix them. How can i avoid this problem?
