Is there a piece of corrosion right on the forward, leading edge?
Your analysis seems plausible to me.

you might be able to confirm this by placing the calculator on a table and gently pressing the front face (on the top left- and right corners) while trying to turn on the calculator. It sounds like it may be a broken post to me, though.

My guess would be that the front pair of the four port block locating pins are sheared off along with damage to the bosses for the long case screws.

Hi Pauli, if you need help with it, remember I'm just 80 klms south of you.
Cheers,
John

Thanks for the idea. I feared a broken post, I'll know for sure when I disassemble. Sad really, the calculator is in great cosmetic condition.

I think I've figured this out. The battery / module connector had slightly flattened foam/felt which is stopping the electrical connection.
I took the connector out and put it into my 41cv and the problem appeared on that calculator. Swap back its original connector and it comes good. At this stage I've not tried swapping the cv's connector into the 41c.
My question now is what is the best way to fix this?
The padding is only very slightly squashed.
