MacBook Pro 15" Unibody Mid 2012 Airport and Bluetooth Antenna Replacement
-
-
Remove the following ten screws securing the lower case to the upper case:
-
Three 13.5 mm (14.1 mm) Phillips screws.
-
Seven 3 mm Phillips screws.
-
-
-
Use the edge of a spudger to pry the battery connector upwards from its socket on the logic board.
-
-
-
Pull the camera cable connector straight out of its socket on the logic board.
-
-
-
-
Remove the 8.6 mm Phillips screw securing the antenna/camera cable retainer to the upper case.
-
Remove the antenna/camera cable retainer from the upper case.
-
-
-
Grab the upper case with your right hand and rotate it slightly toward the top of the display so the upper display bracket clears the edge of the upper case.
-
Rotate the display slightly away from the upper case.
-
Lift the display up and away from the upper case, minding any brackets or cables that may get caught.
-
-
-
Starting on the right side of the display, slide the antenna's plastic cover approximately 1/4" to the right.
-
Then, lift up the right edge of the plastic cover just enough to separate it from the display.
-
Continue lifting the cover along its length, until the entire cover is separated.
-
Remove the plastic cover and retain for reassembly.
-
-
-
Optional: Place a cover on top of your display, just in case your screwdriver slips.
-
Remove the two #000 Phillips screws on the far-right (see detail photo).
-
Remove the somewhat-hidden #000 Phillips screw on the far-left of the display (see detail photo).
-
Remove the six #000 Phillips screws in the middle of the antenna board.
-
-
-
Make sure to re-wrap the Antenna/iSight cables back with some tape. If your replacement part did not include any, reuse the one you took off. My replacement part came with tape, but I still put a bit of Kapton tape around the black tape to completely close the fold.
-
The new antenna hopefully came with the small grounding straps that go around the cables, and get screwed in on the far-right of the display. If they didn't, you'll need to remove them from the old antenna.
-
Insert the replacement board starting with the far-left side. Once inserted, the board should sit loosely in the grooves of the display.
-
When installing the new antenna, first screw in one of the six center screws -- that will help align the far-left screw over its hole.
