Huh? This doesn’t tell how to replace the keyboard.

Jacob Pearlson - Apr 15, 2019

After the last step unscrew the 3 screws at the top of the device holding the display assembly to the top portion, then bend those up and you can pull the whole cover with the keyboard and touchpad off and slide the new one in.
