I suggest adding a step here that addresses the various wires and ribbon cables that connect to the motherboard.
Is there a step missing between this step and the next? How did we get inside the case?
I feel this step needs clarification: Are just lifting the cable away from the shield, or are we removing the cable entirely?
I have only discovered one screw that releases the keyboard. It is under the RAM access panel
Melvyn, I agree. This not up to iFixit's standards.
