结论

Compare your new replacement part to the original part—you may need to transfer remaining components like the watch buttons or remove adhesive backings from the new part before you install it.

To reassemble your device, follow these instructions in reverse order.

During reassembly, apply new adhesive where it's necessary after cleaning the relevant areas with isopropyl alcohol (>90%).

Take your e-waste to an R2 or e-Stewards certified recycler.
