Remove the main board screws

Use a T8 Torx Security screwdriver to remove the three remaining screws securing the main board:
Two 16.3 mm‑long screws securing the APU tension bracket
Don't remove or install one screw at a time, or you may damage the APU. During disassembly and reassembly, alternate between the two screws a half turn at a time to maintain even pressure on the bracket.
One 7.5 mm‑long screw
