Hi everybody,
I have a Casio FX-4500PA calculator and I like it very much, but it has a very annoying problem. It continuously shows the low battery warning, even if I've just changed all the batteries (the calculator have two CR2032, one for the power and one for the data). I've read somewhere on the web that it's a known problem and it's due to the battery contacts on the main board: infacts if I shake it a little bit, the problem disappear. How can I solve this problem? It even happened during two exams (luckily I had another calculator) and I'm so frustrated that I'm thinking to solder wires directly to the batteries.
Thanks for the help.
