I also have a 42S, and have no battery problems with it. I'm not familiar with the insides, but is the 'built in capacitor' for the purpose of maintaining memory while changing batteries? Next question, any idea where it might be located? The HP32S picture at this site shows the back of the circuit board. If it's near the top, I'm thinking I might be able to access and disconnect it from under the battery cover without totally disassembling it. I've already figured out a way to install a small switch to disconnect the battery without completely tearing it apart, but that would mean having erased memory every time I use it.
