HP 41CV Power On - eagre - 07-31-2005 I know I'm coming in very late - I just joined the forum. I have 41CV that I've used since the mid 80's (I earlier had a 35, 65, and 67). Recently it has often been reluctant to turn on, even though the N cells are fresh and the battery contacts are clean. I've heard this is a known problem. What is it? HP no longer suppoirts this calculator, but I have come to depend on it.

Re: HP 41CV Power On - Ronald - 08-02-2005 Hi, Just a quickie: Is the black plastic piece for the electrical isolation still in place between the keyboard and the CPU board, I forgot to replace it one time myself and then I had also some strange behaviour on certain keys. Good luck
