Step 2

              Remove rubber feet and the screws under them

Annoyingly, in many newer laptops, screws are hidden under the rubber feet. This is one of them. Only the circled rubber feet have screws under them, the fourth one does not. Pry them off.

Step 7

              Remove heatsink screws, hinge screws & more

Remove the four heatsink screws surrounding the CPU socket. This is necessary as the heatsink blocks the hinges from being removed.

Turn the hinges away from the palmrest. You may need to use a screwdriver to pry, but be careful if you do!
Remove the antenna connectors from the Wi-Fi card.
