I have an A1200 which TheCorfiot recapped for me last year and when he sent it back I noticed some keys weren't working when I plugged the kb back in. The keypad seems to be the only affected area, only the ( ) and / keys will work over there none of the numbers or return key etc.

Today I finally decided to try the kb from my other A1200 (TC recapped this one too) to see if that was the problem. I connected it up and to my surprise the exact same thing happened using that kb as well. Now I know this kb is good because it was fully working on my main A1200. So I thought this must be a motherboard problem, I put the good kb back into my main machine and turned it on.... now the same keys that will not work on the other kb have stopped working on this one too!

I put the other kb in to test that one there as well and now i have two kb's with most of the keypad not working on either machine.

At this point i thought let's check if it's the boards somehow... and got the kb adapter out of my A1200 tower. Plugged that in and connected up an A2000 kb.... works perfectly on both main boards.

Any ideas what has happened to the A1200 kb's and how they can be fixed?
