Thanks to merge to this post, I didn't find it before....

Hello to everyone

After changing a motherboard to similar one due a catastrophic failure, it can't recognize keyboard, touchpad and sound card despite it being the same motherboard model.

Reading similar posts, I decided to capture BIN files using a SPI programmer from BIOS and EC chips. I dumped it into new motherboard, but model, SN and SNID are empty on the new BIOS menu, so I concluded to DMI data is empty. I can't find how to program DMI data into the new motherboard, so I'm requesting help.

Model : A314-22
SNID : 02300515376

Hello to everyone, I'm a computer engineer from Chile. Actually I'm repairing laptops from basic reinstallations to complete reassembly. But some of works are more complicated than others. I've arrived here investigating how to copy DMI data to one motherboard to another, but it's for another topic and post. Thanks to everyone to build a community as this....
