STEPS:

Tools You Need

For this repair, you will need a pentalobe screwdriver, a T3 and T5 Torx screwdriver, a plastic pick or spudger, isopropyl alcohol, paper towels, a magnet tray or magnetic pickup tool, and tweezers to assist with tight connectors.

Inspect Internal Damage

• Noticeably swollen and punctured battery is visible upon opening.
• Clean the interior thoroughly before proceeding.
• Identify all cables and screws that must be removed for safe battery extraction.

---

Disconnect the Trackpad Cable

• Lift the bracket and disconnect the trackpad cable.
• Bend the cable gently out of the way to avoid interference.

---

Disconnect Battery Daughterboard Cable

• Flip open the retention bar and disconnect the cable carefully.
• Use a T5 screwdriver to remove the screw securing the battery bracket to the logic board.
• Lift the bracket out and bend the cable aside.

---

Fully Disconnect Battery

Remove Speakers for Easier Access

• Disconnect the speaker ribbon cables carefully.
• Pry up both speakers after applying more alcohol for easier removal.

---

Pry Out Battery Cells

• Use a flat spudger to lift battery cells from the sides.
• For tight areas, switch to a smaller spudger for better leverage.
• Remove the entire battery unit carefully and set aside.

---

Clean Remaining Adhesive

• Scrape off leftover adhesive strips using paper towels.
• Ensure surface is clean and smooth for new adhesive application.

---

Lay New Adhesive

• Do not press fully until the center T5 screw is secured.

---

Reinstall Speakers

• Clean leftover glue before reinstalling speakers.
• Align speakers carefully with previous placement.
• If misaligned, remove the battery and realign everything before proceeding.

---

Reconnect Components

• Plug speaker cables back into the board and secure retention bars.
• Replace tape over connectors to protect from movement.
• Reconnect the battery daughterboard cable: larger end to logic board, smaller end to battery.

---

Reconnect the Trackpad Cable

• Click the trackpad cable into place.
• Reinstall the metal bracket with T3 screws to secure the cable.

---

Reattach Bottom Case

• Align the six fingers at the top of the bottom case with the top case.
