My Surface 2 is locking up every 15 mins of not doing anything (Idle). I have already change the group policy on the surface to read 9999 as well as changed the settings on the Advance power options to read never etc. on the battery power settings. Last I have disable the screen saver as well. The Tablet will go on lock mood after 15 mins of being on idle. The odd part is that once in the lock screen it doesn’t go to sleep or hibernate. Because of course I change the settings. Any ideas what it could be or perhaps I am missing a step or advice.
