Some keys stopped working

Giancarlo,

Thank you very much for your reply.

Your suggestion worked.

I went to the http://www.youtube.com video ( https://www.youtube.com/watch?v=O0dhnNFSGEQ - it was in French! ) and viewed how to disassemble the HP Prime without damaging it.

Also like you, the two ribbon cables did not seem disconnected.

The first time I tried, I wiggled the ribbon and pressed in the ribbon connectors without removing the protective clear tape over the electronics and the buttons still did not work.

In the second attempt, I removed the protective clear tape and then wiggles the wires and pressed in the ribbon connectors and then functionality returned to the buttons.

Again, thank you for your help.

I hope the ribbon cable will stay connected - Cheers!
