issue only happened since updating to FE-Update 1 on my X1000. boots fine but if I don't use it for quite a while (2+ hours etc), the screen turns on but system is crashed. no guru. no soft-boot. only thing left to do is shut it off.
actually a few times the same issue has happened immediately after boot up...restarting has solved it BUT this type of behaviour has never happened before updating to FE-Update 1. ???
