There are 9 sets of screws (M2x4) that secure the motherboard in place, which need to be removed. One screw is hidden under a small Lenovo sticker, marked in orange. Removing the sticker will reveal that the motherboard has been repaired.
Each screw securing the motherboard is marked with a small triangle, which helps identify the correct screws for reassembly, as some holes require multiple layers to be screwed together.
The two rectangles represent cords that connect the main motherboard to the side motherboards. For our purpose, disconnect the cord marked in blue.
