Hey all.
I just bought a Casio Algebra FX 2.0 plus from ebay. It arrived , was working , but there was a moving part inside it. I got curious and opened inside it. I saw the moving part was a capacitor ( a small black cylinder, 3 things written on it, "10V" - "1000micro farad" - "SMG"). It was probably thorn apart from the calculator while shipping.

From what I learned at school , capacitors are for holding electricity like a battery. My question is how is it possible that the calculator works perfectly without this part? Anyone knows what is the use of such capacitor in a calculator? Do you think there will be problems in the future? Should I just solder it in its place?

Thanks for your helps.

I dropped my calc to the floor once, after that something has been moving around inside *heh*

Since it still works perfectly, I never cared to open it though.. (assumed it was just a piece of "useless" plastic the fell lose)

Capacitors are used to deliver higher amount of energy than what would be available straight from batteries.

The use of it in a calculator is propably to make the lcd screen turn on (only quessing here).

Yes you should try to solder it in its place if possible else you may meet with strange problems in the future...
