Many thanks for your help Adam & tribble
I will try a last solution... The problem is since 2 days, the screen didn't turn off...
Always the loading screen with beautiful white squares...
I'm demanding when if my iLiad will turn off...
To reboot, I have to click the reset bouton and hold the power switch...
I will try tonight to format the CF...
Wait my screen to turn off at last and try to switch on holding the connect button...
I will inform you asap
