MacBook Pro 15" Retina Display Mid 2012 Logic Board Assembly Replacement

Step 1 Logic Board Assembly

• Use the flat end of a spudger to pry the headphone jack connector up from its socket on the logic board.
Step 2



• Use the flat end of a spudger to pry the left speaker connector up and out of its socket on the logic board.
• Use the tip of a spudger to pry the right speaker connector up and out of its socket on the logic board
• Be sure to pry on the cable head, and not on the socket itself. Prying on the socket may cause it to separate from the logic board.
Step 3
• Peel back any tape covering the keyboard ribbon cable connector.
Step 4
• Use the flat end of a spudger to flip up the retaining flap on the keyboard ribbon cable ZIF socket.
• Pry only under the hinged retaining flap, not the socket itself, or you may break it off the board.
• Use the flat end of a spudger to gently back the keyboard ribbon cable out of its socket by pushing first at one side, then the other.
Step 5
• Use the flat end of a spudger to pry the trackpad ribbon cable connector up from its socket on the logic board.
Step 6
• Use the flat end of a spudger to pry the keyboard backlight connector up from its socket on the logic board.
Step 7
• Use the tip of a spudger or your fingernail to flip up the retaining flap on the microphone ribbon cable ZIF socket.
• Be sure you are prying up on the hinged retaining flap, not the socket itself.
• Pull the microphone ribbon cable out of its socket.
Step 8
• Use the tip of a spudger to pry the display data cable lock and rotate it toward the DC-In side of the computer.
• Pull the display data cable straight out of its socket on the logic board.
• Do not lift up on the display data cable, as its socket is very fragile. Pull the cable parallel to the face of the logic board.
Step 9
• Use the flat end of a spudger to carefully pry off the rubber screw cap on the raised screw head near to the MagSafe 2 connector.
Step 10
• Remove the following six screws securing the logic board to to the upper case:
• One 2.6 mm T5 Torx screw
• Two 5.8 mm T5 Torx screws
• One 3.8 mm T5 Torx screw
• One 5.2 mm Raised Head T5 Torx screw
• One 3.5 mm Silver T5 Torx screw
Step 11
• Lifting from the side nearest the battery, rotate the logic board toward the top of the MacBook Pro.
• Using the flat end of a spudger, carefully push the MagSafe 2 connector out of its socket on the bottom of the logic board.
• When reinstalling the logic board, check the cables at the marked locations to make sure they don't get pinned underneath the logic board.
• Clockwise from top: keyboard, trackpad, battery, right speaker, keyboard backlight, display, microphone, headphone jack, left speaker.
Step 12
• Remove the logic board assembly from the MacBook Pro.
