STEPS:

Tools You Need

For this repair, you will need a Pentalobe screwdriver to remove the bottom screws, a suction cup for lifting the bottom cover, a plastic spudger for safe cable disconnection, a T5 Torx screwdriver for Wi-Fi module and logic board screws, a T3 Torx screwdriver for display and hinge-related components, and a PH1 screwdriver for Wi-Fi vent module fasteners. Optional tweezers are helpful for guiding cables during reinstallation.

---

Remove Bottom Case

• Flip the MacBook over and remove the six pentalobe screws on the bottom case: four short ones at the bottom and two long ones at the top.
• Use a suction cup or your hands to lift and loosen the bottom case from the frame.
• Slide the bottom case outward by pushing the top away and pulling the bottom toward yourself to release the internal latches.

---

Disconnect the Battery

• Use a plastic spudger to disconnect the battery management flex cable first.
• Remove the T5 pancake screw securing the battery jumper from the logic board to the battery board.
• Once these are disconnected, the MacBook is safe to work on internally.

---

Remove T5 Screws from Wi-Fi Vent and LCD Board

• Using a T5 screwdriver, remove four screws holding the Wi-Fi vent module and LCD board to the top case.
• Unplug the Wi-Fi antenna cables before removing the T5 screw that secures the antenna bracket.
• Set the T5 screwdriver aside once this part is complete.

---

Disconnect LCD Proximity Sensor

• Switch to a T3 screwdriver and remove the two screws securing the LCD proximity sensor.
• Unplug the sensor from the logic board; it controls screen sleep/wake functionality.
• Carefully lift the sensor out and set it aside.

---

Remove Hinge Covers

• Still using the T3 screwdriver, remove four screws (two on each side) to release the LCD hinge covers.
• Remove the hinge covers completely to expose the LCD hinge area.
• Set covers and screws aside for later reassembly.

---

Remove LCD Bungee Screws

• With the T3 screwdriver, remove four long screws securing the LCD bungees that help with hinge tension.
• These can be stubborn; even when loose, they might require gentle wiggling to remove.
• These screws ensure hinge resistance and help hold the screen’s position.

---

Remove LCD Display Connector Bracket

• Still on T3, remove four screws securing the LCD display connector bracket: two short screws at the top and two longer ones at the bottom.
• This bracket protects the display cable from being kinked or damaged.
• Once removed, lift the bracket and unplug the display cable.

---

Remove Wi-Fi Vent Module Screws

• Use the PH1 screwdriver to remove all screws on the Wi-Fi vent modules on both sides of the logic board.
• Be sure to collect and organize these screws for later use.
• These modules include cable routing and protective structures near the hinge.

---

Remove Hinge Screws

• Use a T8 screwdriver to remove the six screws (three on each side) securing the LCD hinge to the bottom case.
• Hold the screen firmly while doing this to avoid it falling or shifting.
• Once screws are removed, the display assembly is free from the MacBook.

---

Remove Old LCD Assembly

• Disconnect the LCD display connector if not already done.
• Open the MacBook and carefully lift off the top case with the damaged LCD.
• Set aside the damaged display and prepare the new screen.

---

Prep and Install New LCD

• Open the hinges of the new LCD to make insertion into the base easier.
• Carefully lift and guide all cables through the top case cutouts as you lower it into place.
• Close the unit slightly while holding the hinges to avoid pinching or damaging cables.

---

Secure Hinges with T8 Screws

• Using the T8 screwdriver, reinstall the six hinge screws to secure the new display to the bottom case.
• Tighten all screws evenly to ensure smooth and stable hinge movement.
• A loose hinge may cause the screen to close on its own.

---

Reconnect LCD Proximity Sensor

• Plug the proximity sensor back into its port on the logic board.
• Confirm the hook on the logic board side is aligned correctly before securing.
• Fasten with the two T3 screws previously removed.

---

Reinstall LCD Bungees

• Insert and align the bungee tension screws with the T3 screwdriver.
• You’ll feel a slight snap when the alignment is correct.
• These screws help maintain display tension and alignment.

---

Reinstall Wi-Fi Vent Module and Cables

• Guide Wi-Fi cables through the heat pipe cutout near the right hinge.
• Use tweezers if needed to route cables correctly and prevent pinching.
• Align and reinstall the Wi-Fi vent module.

---

Reconnect Wi-Fi Antennas and Secure Brackets

• Plug in all Wi-Fi antenna cables into their respective sockets.
• Use the T5 screwdriver to secure the bracket that holds the antenna cables in place.
• Secure the Wi-Fi module and LCD board with the remaining T5 screws

---

Reconnect LCD Display Connector

• Plug in the LCD display connector to the top of the logic board.
• Reinstall the bracket over the connector using two short T3 screws at the top and two long ones at the bottom.
• Confirm all cable connections are firm and secure.

---

Secure Touch Bar and Sensor Bracket

• Reinstall the bracket that holds the Touch Bar connector and proximity sensor.
• Align the hook side before screwing down with two T3 screws.
• Confirm the bracket is flush with the board.

---

Reinstall PH1 Screws on Vent Module

• With the PH1 screwdriver, reinstall all screws on the Wi-Fi vent module.
• Start from the outer screws and work inward for even pressure.
• Double-check cable paths to ensure nothing is pinched.

---

Replace Hinge Covers

• Reposition the hinge covers over the hinges.
• Use the T3 screwdriver to reinstall the four screws that secure them.
• Ensure the covers sit flush and don’t block hinge movement.

---

Reconnect Battery

• Use the T5 screwdriver to secure the pancake screw that connects the logic board to the battery board.
• Plug in the battery management flex cable to re-enable power monitoring.
• This step is critical for power-up, charging, and battery status.

---

Test Before Reassembly

• Plug in a charger to confirm the MacBook powers on and displays correctly.
• Confirm that it charges properly and stays on when unplugged.
• Check the proximity sensor by closing the lid and waiting for sleep mode activation.

---

Replace Bottom Case

• Align one corner of the bottom case slightly offset, then slide it forward to engage the fingers.
