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.

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.

Could be a bad battery(CR2330) power problem of Airport Extreme A1521 router?

Vadim - Reply

I’ve opened quite a lot of broken A1521 and always checked the battery. None of them worked with a new battery or due to the “reset”

Sorry…
