I am very reluctant to open the calculator as the Spice case is very brittle and the screw posts break very easily (ask me how I know).

Except for this the calculator in in great shape but I'd love to have it work as it should.

Any ideas?

Hi Moggul, may I know please if, performing the selftest, you get an error message ?
If you break the posts (I hope not so), it'easyer, anyway, to fix them and of course you should not worry, at least, to compromise the calculator's functionality like it could happen with other machines (41), don't be scared of that... maybe the contact of that key is just dirty and just needs to be cleaned...
