STEPS:

Tools You Need

For this repair, you will need a Pentalobe screwdriver to remove the outer case, a T3 and T5 screwdriver for internal components, tweezers for handling pull tabs, isopropyl alcohol (98% or higher) to soften adhesive, and a plastic spudger to disconnect cables and lift delicate parts.

---

Remove the Bottom Case

• Flip the MacBook over and remove all 8 visible Pentalobe screws (10 originally, 2 are missing on this unit).
• Note that the top screws are longer than the sides and bottom.
• Lift the bottom case to reveal the internal components.

---

Disconnect the Battery

• Locate the battery connector and use a plastic spudger to disconnect it from the logic board.
• This step is crucial to safely work on the device and avoid electrical damage.
• Set the battery cable aside gently.

---

Remove Trackpad Retention Plate

• Use a T3 screwdriver to remove two screws on the retention plate holding the trackpad Flex cable.
• Unplug the Flex cable carefully using a spudger.
• On this model, the Flex cable is adhered and goes under the logic board, so handle with care.

---

Detach Trackpad Flex Cable

• Open the MacBook slightly so the trackpad dangles.
• Use the plastic spudger to unlatch and unplug the cable from the trackpad.
• Peel it off gently from the adhesive; do not force if it resists.

---

Unplug and Prepare Speakers

• Disconnect both left and right speaker cables from the logic board.
• Note that the right speaker is glued, while the left is not.
• Handle connectors gently to avoid tearing or ripping cables.

---

Remove Speaker Adhesive Pull Tabs

• Use tweezers to grab the speaker pull tabs and roll to remove the glue strip.
• If pull tabs snap, use isopropyl alcohol to loosen adhesive under the speaker.
• Lift speaker edges carefully with a plastic spudger until fully removed.

---

Remove Battery Retention Screws

• Use a T3 screwdriver to remove the two screws holding the battery bracket.
• These screws are located on either side of the battery connector.
• Set the bracket aside safely.

---

Remove Battery Adhesive Pull Tabs

• Carefully twist and roll each of the six adhesive pull tabs to loosen them.
• Remove them completely to free the battery from the top case.
• If any tab snaps, use alcohol and a spudger to release adhesive.

---

Lift and Remove Old Battery

• Once all adhesive is removed, lift the battery gently out of the chassis.
• Set the old battery aside and recycle properly.
• Clean the surface beneath the battery before installing a new one.

---

Prepare and Install New Battery

• Align the new battery with screw posts and the center of the chassis.
• Press into place carefully, ensuring adhesive sticks.
• Secure it with the original T3 screws.

---

Reinstall Speakers

• Apply fresh adhesive to both speakers and remove protective backing.
• Press each speaker into position, starting with the left then the right.

Reconnect Trackpad Flex Cable

• Open the MacBook slightly and align the washers in correct orientation.
• Feed the Flex cable through the cutout and connect it to the trackpad.
• Close the retention latch once connected.

---

Secure the Trackpad

• Use T5 screws to secure the trackpad—two at each corner and one in the center.
• Ensure it is aligned and does not shift before tightening.
• Double-check washer placement for proper tactile feedback.

---

Reconnect Trackpad to Logic Board

• Plug the other end of the trackpad Flex cable into the logic board.
• Install the retention bracket using two T3 screws.
• Confirm all connections are secure before proceeding.

Reconnect the Battery

Power On and Test

• Test both charging ports to confirm they are working.

---

Reinstall Bottom Case
