Hi, the same thing happened to me yesterday. I was reading, turned the cybook of, and when I turned it on again I got the screen with the "bricks". The battery was not low, and the cybook hasn't been connected to the computer in a week or so. I tried resetting it, charging it, removing the SD card and connecting it to the computer. It now displays the screen with the little book with the dots and nothing happens.
My computer does not recognize it
Up until yesterday I haven't experienced any problems at all - and I already miss it
I have mailed bookeen and hope that they will come back to me soon, but with Easter....
Any suggestions are appreciated
Thanks
