Mine has 12 screws not 9. one card also to remove, (held by screw), and 2 sets of connectors
Plus you need to put the splonger in the edge below the usb connections, not on the area highlighted in the picture above. Yeah there are way more screws than 9. You also need to remove the screws out of any m.2 ssd drives, msata drives, and wlan card. You also need to unplug each ribbon cable, and unplug and unwire the tronlights on both sides of the laptop.

Actually "Step 6" tells you to do just that !!!
