Recently, after I released the MS completely out from my NX70V that was powered off, my finger unintentionally touched the screen and I heard some 'gizz' sound. It seems the CLIE is reacting to my screen touch but, the most strange is, the screen still kept in dark (look like still powered-off). After I turned it on and off again, no more reaction was found in any screen touch.
I wonder if I am not aware of this and let the CLIE keep in such state without powering on and off after I released the MS, it would drain out all my CLIE battery!
