Ok, before its stays in sleep mode untill i got advice to turn it off, and now sleep mode its turned off.
Yes i removed all books, formatted internal memory, removed sd card, restored to deflauts ect.
I tried to contact Sony in Poland because my neglish its not that good ( as you can see ) to contact with UK, but when i'm sended them email they not answered me ( i'm waiting already 4th day ) but i'm not amazed by that i got Sonys Tv and owned PS3 and usually i'm waiting 2-3 weeks for answer without solution ofc, and people on phone can tell you only thing which you can read about reader at sonys site ( no help at all )
