STEPS:

Tools You Need

For this repair, you will need a pentalobe screwdriver to remove the MacBook’s base screws, a suction cup for lifting the bottom case, a T5 screwdriver to detach the battery jumper, tweezers to peel adhesive, isopropyl alcohol (preferably 98% or higher) to loosen glue, and both plastic and metal prying tools to safely remove and replace the speakers.

---

Remove Bottom Case

• Flip the MacBook Pro over and locate the six pentalobe screws securing the bottom cover.
• Note that the two screws on the top right and left corners are longer than the four bottom ones.
• Use a suction cup to carefully lift and remove the bottom case, exposing the internal components.

---

Disconnect Battery for Safety

• Locate the battery management unit flex cable and disconnect it to isolate power.
• Use a T5 screwdriver to unscrew the jumper that links the logic board to the battery board.
• This ensures that the device is safe to work on before proceeding with the repair.

---

Unplug Both Speakers

• Locate the connectors for both the left and right internal speakers on the logic board.
• Carefully unplug each speaker to prepare for removal.
• Avoid applying excessive force to prevent damaging the connectors or board.

---

Soak Adhesive Beneath Speakers

• Using a syringe or dropper, apply 98% isopropyl alcohol under each speaker.
• Allow the alcohol to soak in for several minutes to loosen the adhesive.
• This step minimizes risk of damaging the speaker housing or surrounding components.

---

Pry and Remove Left Speaker

• Begin with a flat plastic prying tool to gently fatigue the adhesive around the left speaker edges.
• Switch to a metal pry tool to further loosen the adhesive if necessary.
• Once loosened, return to the plastic tool to fully lift and remove the speaker from its housing.

---

Remove Right Speaker

• Repeat the same process on the opposite side: use alcohol, then plastic and metal prying tools.
• Gently lift out the right speaker after loosening the adhesive.
• Take care to maintain the integrity of surrounding parts during removal.

---

Remove Remaining Adhesive

• Use tweezers to peel up any adhesive left behind on both speaker wells.
• Reapply isopropyl alcohol if needed to soften stubborn glue residues.
• Ensure the speaker wells are clean, smooth, and free of debris for proper speaker alignment.

---

Clean Speaker Mounting Area

• Moisten a lint-free cloth or swab with isopropyl alcohol.
• Gently clean both speaker wells to eliminate any remaining residue.
• A clean surface ensures proper adhesion and prevents future rattling or distortion.

---

Prepare New Speakers

• Remove the protective backing from the adhesive on the new replacement speakers.
• Confirm that each speaker’s orientation matches its designated side (left/right).
• Handle the speakers carefully to avoid contamination or damage to connectors.

---

Install Left Speaker

• Align the left speaker connector and plug it into the socket before pressing it into place.
• Make sure the adhesive backing is correctly positioned.
• Press down firmly to ensure the speaker is seated securely and flush.

---

Install Right Speaker

• Repeat the same process for the right side: plug in the connector, align the speaker, and press it into place.
• Double-check that both speakers are flat and adhered securely without gaps.
• Apply light pressure for a few seconds to maximize adhesion.

---

Reconnect Battery

• Reinstall the T5 screw securing the jumper between the logic and battery boards.
• Reconnect the battery management unit flex cable to re-establish power flow.
• Ensure all cables are seated correctly to avoid startup or charging issues.

---

Test Functionality Before Closing

• Connect a charger and power on the MacBook Pro.
• Verify that the battery is recognized and charging properly.
• Play audio through the new speakers to confirm they function correctly with no distortion.

---

Reinstall Bottom Case

• Realign the bottom case to its original position over the MacBook frame.
• Reinsert and tighten the six pentalobe screws, remembering the top corner screws are longer.
• Gently press around the edges to ensure the cover sits flush.

---
