Two additional screws not circled need to be removed. One in the upper left (near the foot and circled screw), and one in lower center (at bottom right of RAM, end of STRIKE ZONE wording).
Between steps 8 and 10, the display must be removed; you'll note in step 10's picture that the display isn't there.
1. Detach the ribbon cable that connects the display to the motherboard.
2. Move the display cable and WLAN cable so they don't get caught.
3. Unscrew the two screws in back
4. Lift the display's hinges out of the main assembly.
