Preliminary Steps
Before you begin, run the computer until warm (if possible) to help soften the thermal
material on the logic board, then shut it down and remove the following:
• Battery
• Top case
• Right ambient light sensor board and lens cover, if present
• Display panel assembly – Note: Only need to remove if the hair dryer heating
procedure needs to be performed.
Note: It may be helpful to remove the optical drive and hard drive to reduce the number of
cables to control when replacing the logic board, if desired.
Procedure
Warning: Flexing of the logic board can break solder joints to parts. Guard against
flexing, to prevent damage to the board.
