Introduction
If your speaker needs to be replaced, you can access it with this guide. If needed, you can also replace the case, ribbon cable, CPU PCB, and switch PCB since this device is relatively small and the parts are relatively close together. For this replacement, you'll need a spudger, safe pry tool, T6 Torx screwdriver head, and a T8 Torx screwdriver head.
