Reassembly Notes

Note: Installing a New Top Case

Transfer the touch-pad support assembly from the old top case to the new one.

∙Before installing the screws, make sure the front edge of the plate is held by the four plastic tabs on the top case.

∙Check the click buttons—make sure you can feel the “click” in all four buttons. After assembly, check their operation.

∙Position the speaker on the pins on the bottom case before you install the speaker cover.

∙If the slider came off the module latch, attach it to the latch before you install the speaker cover.

Hint

On the bottom case, the holes for the top case screws are unmarked. The hole recesses have flat bottoms for the 16-mm T-head screws and tapered bottoms for the longer 19-mm flathead screws.
