Thank you Ken for your answer, I will work on my H2O tomorrow, and I will sure post an update church mouse.
About my batteries issues, it seems that it works fine for a long time in sleep mode, with the cover printed on the reader.
And (I suppose) randomly, I find it with my last page printed and my batterie empty, so I guess that it waked up itself without going back to sleep mode.
I have verified that nothing can act on the button, and it never happened with Nickel.
Thanx again for your help
