Solved: Installed X220 keyboard in X230 - Ctrl keys don't work?
Solved: Installed X220 keyboard in X230 - Ctrl keys don't work?
As per title - I performed this mod, isolating the leftmost three but one contacts on the underside of the keyboard ribbon connector. All keys work (well, those which work without the BIOS mod that is), except for left & right Ctrl. "sudo showkey -s" shows no output when either is pressed. Checked BIOS for Fn/Ctrl swap, which was disabled. Before I take the whole thing apart again, any ideas what may have caused this? Did I isolate the wrong contacts?

Re: Installed X220 keyboard in X230 - Ctrl keys don't work?
Success! I took everything apart again, and had a closer look at the tape under my microscope; I had missed a tiny sliver of one of the contacts, and the other side was unnecessarily close to the next uncovered contact (perhaps its thickness prevented the other half from making contact?). I carefully removed it with a needle and applied a new piece of tape, which looked much neater - reassembled and hey presto, both Ctrl keys now work. Was it the tape that caused the issue? Without a pinout for the connectors I can't be sure of that; maybe some dust got trapped that was dislodged on second disassembly? It's hardly a dust-free lab I'm working in... In any case, all's well that ends well. Photos below.
