Introduction

The logic board is the main component of the device. It has all the major components for the device to function properly: USB ports, WLAN and LAN ports, and router chips. Because of the many functions the logic board performs, it requires a fan and heat sink to prevent it from overheating. This guide requires you to remove many small screws; use the magnetic mat to prevent losing these screws.

Four black internal wires, three thin and one thick, are connected to the logic board: three by small end clips and one by a larger end clip. Handle the clips gently; they break easily. To detach the small clips from the connectors, place the flat end of the plastic spudger underneath the clip and gently lever it away from the center of the device.

Using two fingers, pinch the power supply wire and gently lift it upward. Move it away from the metal plate. Next, unscrew the four 3.3mm T8 Torx screws and remove the metal plate. The metal plate fits snugly into the gap. To reassemble the device, push the rounded edge of the plate into the gap first. This will wedge the gap open so that you can fit the rest of the plate into its proper place.

  • Loosen, but do not remove the two screws at the bottom of the 1.2-inch wide gap in the middle of the internal structure.

  • These screws are spring-loaded and will stay in the device, even when loosened; however, it is still possible for them to be fully removed. Be careful to only partially loosen them.

Using only your fingers, gently compress the internal structure and pull evenly upward to remove it from the white case. When you put the internal structure back into the case, gently compress it, and lower it most of the way into the case. Stop lowering it when the top port has just entered the case. Now push the two sides of the internal structure outward against the sides of the case.

  • Finish lowering the internal structure the rest of the way into the case. The ports should be lined up with the openings in the case and should be flush against the sides of the case.
