Logic Board
Replacement Procedure
Warning: Flexing of the logic board can break solder joints to chips. To prevent
damage to the board, guard against unnecessary flexing. Do not hold the board by
the ports end or by the narrow neck at the fan cutout, as the board’s weight can flex
the board at this narrow point.
1. Verify that the replacement logic board has EMI shields attached, as shown. If not,
transfer the shields from the replaced board, or replace with a new shield kit.
