I've had a similar model.

Does the keyboard work? If not, do you at least have a Num Lock LED?
If nothing works, you could open up the keyboard case (clips best unclipped with wide flat screwdriver, Philips screws) and check if the cable has been disconnected or damaged internally.


Leds works ...

Hi there,
I have an old Cherry G81-3090 from a Schneider PC of 1991-1993. Great keyboard.

The error messenge is the one from the post title. Cable seems OK. What else could I check?

Thanks a lot
