Wyatt is correct that the black wire in the center can be removed from the top motherboard, but it doesn’t do any good to do so as there are two other sets of wires (grey and black twisted pairs leading to the left and right trigger) preventing you from removing the bottom motherboard entirely. These wires are visible in the pictures of this guide.

I have a 17-x051nr but the steps are exactly the same. Thank you! (I never like peeling off the bottom feet unless I know for sure there’s a screw under there)

Thank you for this guide! I added two small corrections but the guide was very helpful as-is.

There are 14 screws, not 16. The two red circles in the bottom-right (of the first picture in this step) are not screws.

There are 4 screws holding the battery in. Not sure what the bottom center red circle is indicating in this picture (the one below the trash can icon on the battery).

I learned the hard way that we should be lifting from the short side of the connector, not the long side as shown here. The gold pins inside the FPC socket are very fragile and more likely to break when lifted as shown in this picture.
