Orient the display assembly so that the mounting points for the ribbon cable retention clip are closer to the inner wall of the machine. Insert the right-hand side of the display assembly between the two plates of the top shell. Raise the display assembly into place, ensuring that the four cutouts in the display assembly are aligned with the four threaded posts in the top shell.
For each of the four threaded posts, place one washer on the post and loosely thread a retention nut into place. Tighten the nuts with the 5.5 mm socket driver until finger tight.
Step 3: Reconnect the display ribbon cable
Insert the display ribbon cable into the connector on the new display assembly, orienting the exposed contacts on the ribbon cable as they were on the old display assembly. Ensure that the ribbon cable is not twisted or folded.
Step 4: Secure the display ribbon cable
Rotate the latch towards the display assembly to lock the display ribbon cable in place. The latch is locked when it is parallel to the display assembly.
Align the display ribbon cable retention clip with its mounting points on the top shell, ensuring that it holds the ribbon cable flat against the display assembly. Insert one 1.5 mm hex screw into both of the two screw holes in the retention clip and, using a 1.5 mm hex driver, tighten until finger tight.
