Solved! Lenovo Thinkpad S1 Yoga Issues: Keyboard and Trackpad not working

[chains65212]

I have this unusual problem with my Lenovo PC. A couple of years ago, my PC suffered water damage, and it wouldn't start up. I took it to GeekSquad to see if they could repair it. They said the motherboard was damaged, so I bought a new one and replaced it. It powered on just fine, but for some reason the keyboard and trackpad don't work. There are some weird circumstances in which they do however. The laptop is a 2 in 1, laptop/tablet. When the laptop is bent so it is a little past horizontal, the keyboard and trackpad work. Also, in startup, I can enter BIOS without having to use an external keyboard or mouse. I've tried updating the drivers through device manager, but all the drivers are up-to-date. Does anyone seem to know what is going on? (My laptop runs Windows 8.1, I don't know if that is useful information, just letting you know).

It´s not a software problem.
Check the connections of the keyboard/trackpad to the motherboard
replace the keyboard and trackboard

I'm not much of a tech guy, where would the keyboard and trackpad connect to the motherboard? There are certain ribbons that connect it correct?

Touchpad should be the one pulled first in this video, 3rd and 4th the keyboard:
