P150sm-a keyboard and trackpad not working even in bios after replacing motherboard.

[kg42]

Hello,

I recently bought a replacement motherboard for my clevo p150sm-a same board model from aliexpress. Everything worked except for the keyboard and the trackpad. The bios version is at 1.03.11 and its KBC/EC firmware at 1.03.08. I'm thinking it has something to do with the KBC/EC firmware? Does anyone happened to have a bios file so I can test it with different versions? Also usb keyboards and mouse works.

Thanks!

Maybe you didn't plugged the ribbon cables properly ?

I did, i even tried using the old motherboard and test out FN+2 for fan speed (since the function still works even if the board is broken), the keyboard worked but for the new motherboard it wont even detect it. Is it possible that the connectors are damaged in the replacement motherboard?

Sounds like a motherboard problem indeed.
