Hi! Last Friday I was reading as always in my ereader in the bus going back home and after I didn’t turn it off (I thought I was going to read more at home). It stayed like that all weekend and yesterday I took it for reading again but it was stuck in waiting mode, I couldn’t turn it on or off, I thought it was empty so I charged last night. When I picked it up this morning I’ve discovered that it reset itself. What has happened?!!
