STEPS:

Tools You Need

For this repair, you will need a suction cup for removing the bottom case, a Pentalobe screwdriver for the exterior screws, T3, T5, and T8 screwdrivers for internal components, a PL1 screwdriver for the Wi-Fi vent module, and a pair of tweezers to help with tight spaces and pulling antenna cables through. A clean and organized workspace is essential due to the number of small components involved.

---

Remove the Bottom Case

• Start by removing six pentalobe screws from the bottom of the MacBook: two at each top corner and four across the bottom.
• Use a suction cup to gently lift and remove the bottom case from the MacBook.
• Set the case and screws aside safely for reassembly later.

---

Disconnect the Battery

• Disconnect the battery by first unplugging the battery management unit flex cable.
• Use a T5 screwdriver to remove the screw securing the battery jumper that connects the logic board to the battery.
• This ensures the unit is safe to work on and prevents power flow during repair.

---

Remove LCD Connector and Hinge Covers

• Using a T3 screwdriver, remove four screws and two retention plates securing the LCD display connector.
• Disconnect the LCD display connector.
• Remove the hinge covers at the top left and right corners—each held in place by two T3 screws.

---

Remove Right Side Retention Brackets

• Continue using the T3 screwdriver to remove additional retention brackets on the right-hand side of the board.
• Identify and remove the center T3 screws that anchor the logic board in place.

---

Disconnect All Internal Connectors

• Unplug connectors in this sequence: headphone jack, Touch ID, left speaker, trackpad, keyboard cable, right speaker, CPU fan breakout, backlight, and Touch Bar.
• Disconnect the Wi-Fi antennas from the top right side of the logic board.

---

Remove Wi-Fi Vent Module Screws

• Use a T5 screwdriver to remove the screws securing the Wi-Fi vent module.
• Remove any remaining T5 screws that are still holding down the logic board.

---

Unscrew Heat Pipes

• Switch to a T8 screwdriver to remove screws located on either side of the heat pipes.
• These provide cooling to the CPU and are connected directly to the board.

---

Final Screw and Hidden Connector

• Remove one final T5 screw located at the center, near where the Wi-Fi antenna cables exit.
• Disconnect a small hidden connector nearby that was previously overlooked.

---

Remove Wi-Fi Vent Module

• Switch to a PL1 screwdriver and remove all screws securing the Wi-Fi vent module to the top case.
• Carefully cut away the glued rubber grommets from the fans to fully release the module.

---

Remove the Logic Board

• Gently lift and remove the logic board from the chassis.
• Flip it over and remove two T3 screws that secure the display connector for transfer to the new board.

---

Remove the Cooling Fan

• Use the T3 screwdriver to remove the screws holding down the CPU cooling fan on the left side.
• Disconnect the fan cable and lift the fan out of the unit.

---

Remove the Touch ID Module

• Unscrew the bracket holding the Touch ID in place using T3 screws.
• Peel up the adhesive cover and unlatch the connector to release the Touch ID.
• Carefully remove the glued-down Touch ID sensor and its cable assembly.

---

Install New Touch ID

• Feed the new Touch ID assembly through the backside of the MacBook and align it in place.
• Fold the cable back into position and reattach the retention bracket using the same T3 screws: two black screws in the center and four silver ones in the corners.

---

Reinstall the CPU Fan

• Place the cooling fan back in its original position and reconnect its cable.
• Secure it with T3 screws to ensure proper cooling functionality.

---

Transfer Display Connector

• Remove two T3 screws from the display connector on the old logic board and transfer it to the new board.
• Ensure it is positioned exactly as before to maintain a clean installation.

---

Install the New Logic Board

• Carefully place the new logic board into the chassis, ensuring no cables are trapped beneath it.
• Start connecting all cables before screwing it down to prevent mistakes.

---

Connect and Screw Down Logic Board

• Begin with T8 screws at the top left and right sides of the logic board.
• Reinstall the Wi-Fi vent module using tweezers to pull antenna cables through the tight slot.
• Secure the Wi-Fi module with a center T5 screw and PL1 screws on each side.

---

Finish Logic Board Reassembly

• Install the LCD display connector and re-secure it.
• Reattach all screws for the logic board using T3 and T5 screwdrivers as appropriate.
• Replace all retention brackets, hinge covers, and final T3 screws.

---

Reconnect Battery and Finalize Reassembly

• Use a T5 screwdriver to reinstall the screw connecting the battery jumper to the battery.
• Plug in the battery management unit flex cable to the board and replace the cover.

---

Test and Reassemble Bottom Case

• Plug in a charger and check for signs of power and charging.
• Boot the MacBook to confirm it reaches the desktop.
• Once confirmed, reattach the bottom case using the original six pentalobe screws, remembering the two longest ones go in the top corners.
