I had a very long answer and very detailed, but the internet cut me off saying diagnose connection problems even though there were not any, mayby because it was too long of an answer and I was timed out? Anyway, I know you have tryed everything and I do feel for you and I think it would be helpful if it could be docuumented, the feeding leaf behaivor you are explaining, I know it may sound strange but there is the possibility, perhaps, that this is a " personality" behaivor that was put into Pleo Rb, the one you describe. A lot like a two year old having a temper tantrum, Since the Pleo does not scream while the leaf is in it's mouth, it seems happy when eating. Perhaps this is a temper tantrum your Pleo rb is exhibiting. Have you tryed just feeding him his leaf, and when he is done, take it away, If he starts crying, screaming, just IGNORE HIM, see what he does if you do nothing no more feeding the leaf for the rest of the battery cycle. What is the worst he can do, Scream or cry....? He is already doing that, so why not feed him Normally once a battery cycle, and then leave him be. Either he will keep on screaming and crying, tire himself out and shut down and go to sleep, or just maybe he will get tired of crying and do something else if he is not gettting any attention and his leaf. ( the leaf almost seems to be like a pacifier at this point) When he has the leaf in his mouth, does he sing or make any other nosies or just chewing, burping food associated noises? If he was myne, I would document his strange behaivor and feed him once and then ignore him and if it continues show it to Innova , on video tape and let them take it from there since you have tryed everything else, He may just have Temper Tantrum Two behavior and be that very very moody or spoiled Pleo Rb personality that needs strong parenting skills.

Good luck.
If nothing else, at least he is not a human baby and you can shut him off and get your sleep and it is interesting behaivor.
