Reassembly Notes

Note: Installing a New Top Case

Transfer the following items from the old top case to the new one: Touch pad and support.

Left hinge support.

Press down on the touch pad support plate while sliding it into place. Make sure the support is held down at its left and right edges. Check the action of the click buttons before installing the top case.

Engage the tab at the front of the top case, then lower the top case onto the bottom case.

It may be easier to plug in the touch pad flex cable while you are lowering the top case onto the bottom case—rather than waiting until after the top case is fully installed.
