Step 13 — Battery & Logic Board
Gently pull back the white plastic framework to free the left edge of the logic board. Pull up on the logic board slightly to prevent the logic board from falling back into place.
Step 14
Repeat the same procedure on the opposite side to free the logic board from the white plastic casing.
Step 15
Lift the logic board up to disconnect it from the memory board beneath. Don't remove the logic board from the iPod yet, because it's still connected to the battery.
