My motherboard died on my X1 Carbon Gen 1. I sent it to lenovo and the repair estimate was ~0. I decided to replace it myself but the part for my system FRU 04X0495 (W8P,i7-3667U,8G,F,AMT,TPM,MT) new are quite expensive. I found a new system board FRU 04Y1988 (W8P,i7-3667U,8G,F,AMT,TPM) at a much more reasonable price and installed that. I now have a working machine (new machine type 3448-3Y2) but no touchscreen.\n\nQuestion, Is there any way to convert or add to my new system board the touch screen capability? Is it built into the boards circuity? An add on component. I assume it is not just the driver? Anyone have any experience with this.
