REPAIR TIME & SKILL LEVEL:

This repair is estimated to take about 1.5 to 2 hours to complete and is of INTERMEDIATE difficulty, requiring careful handling of components and knowledge of MacBook internal parts.

STEPS:

Tools You Need

For this repair, you will need a Pentalobe screwdriver to remove the screws on the bottom case, a T5 Torx screwdriver for internal components, a suction cup tool for lifting the bottom case, and isopropyl alcohol (90% or higher) to soften adhesive. Additionally, a plastic pry tool or spudger will help remove the battery and other internal parts safely.

---

Remove the Bottom Case

• Use a Pentalobe screwdriver to remove the screws holding the bottom case of the MacBook.
• There are several screws to remove — make sure you note their sizes.
• Once all screws are removed, use a suction cup to gently lift the bottom case away from the MacBook.
• Carefully push the top case away and pull the bottom case toward you to release the clasps on the front.

---

Disconnect the Battery

• Once the bottom case is removed, you’ll be able to access the battery.
• Peel back a taped cover to reveal the battery management unit flex cable and connector.
• Use your T5 screwdriver to disconnect the battery management unit cable.
• Also, remove the jumper from the battery daughter board using the same T5 screwdriver.
• This makes the unit safe to continue working on.

---

Remove Trackpad to Avoid Damage

• Using the T5 screwdriver, remove the screws securing the trackpad’s flex cable to the mainboard.
• Once these screws are removed, peel the trackpad flex cable away from the battery.
• For first-timers, we recommend removing the trackpad entirely to prevent any damage when removing the battery.
• Carefully unscrew the four screws on each side and two screws in the center that hold the trackpad in place.

---

Remove the Trackpad

• Open the unit slowly and carefully feed the trackpad flex cable through a cutout in the MacBook.
• Ensure the trackpad standoff washers are not lost, as these are essential for proper trackpad function.
• When the trackpad is removed, place it aside carefully.

---

Break the Adhesive on the Battery

• Apply isopropyl alcohol (90% or higher) around the edges of the battery to soften the adhesive.
• Wait a minute for the alcohol to break down the glue.

---

Remove the Battery

• Using a spudger or pry tool, carefully work under the battery without applying excessive pressure.
• Pry the battery loose from the unit, starting from one side, then move along the center and other side until the battery is free.

---

Remove the Battery Management Unit Flex Cable

• Use the T5 screwdriver to remove the screws securing the battery management unit’s flex cable.
• Disconnect the flex cable from the battery connector, ensuring it’s removed cleanly.

---

Remove Remaining Adhesive

• After removing the battery, use more isopropyl alcohol to soak any remaining adhesive strips.
• Use a metal spudger to scrape off the remaining adhesive gently.
• Be careful not to damage the top case during this process.

---

Clean the Area

• Clean the area thoroughly to ensure no leftover adhesive or residue remains.
• Use a dry cloth to wipe off any excess isopropyl alcohol and let the surface dry.

---

Install the New Battery

• Take the new battery and peel off the protective covers from the adhesive strips.
• Align the battery carefully, starting with the middle section, then position the cables running to the second and third cells.
• Apply even pressure to ensure the battery adheres securely to the case.

---

Reconnect the Battery Management Unit Flex Cable

• Insert the smaller end of the flex cable into the battery connector, ensuring it fits correctly.
• Attach the larger end of the flex cable to the logic board, ensuring a secure connection.
• If the battery is not charging correctly, re-seat the cable or replace the flex cable entirely.

---

Reinstall the Trackpad

• Place the trackpad back into the unit and ensure the flex cable is properly positioned.
• Carefully feed the flex cable through the cutout and reconnect it to the mainboard.
• Secure the trackpad with the eight screws — four on each side, and two shorter screws in the center.
• Tighten all screws just enough to keep them secure, but avoid overtightening, as this can affect trackpad function.

---

Reattach the Trackpad Retention Bracket

• Reinstall the retention bracket for the trackpad flex cable using the T5 screwdriver.
• Ensure the screws are secured tightly, but do not overtighten to avoid damaging the flex cable.

---

Secure the Battery Jumper

• Use the “pancake screw” to secure the jumper between the battery and logic board.
• Tighten this screw fully to ensure proper contact between the pads.

---

Reconnect the Battery Management Unit Flex Cable to the Logic Board

• Reconnect the battery management unit flex cable to the logic board.
• Ensure it’s fully seated to guarantee that the battery will function properly.

---

Reinstall the Taped Cover

• Reattach the taped cover over the battery management unit and flex cables.
• This helps protect the internal components from dust and other debris.

---

Attach the Bottom Case

• Place the bottom case back onto the MacBook and slide it into position.
• Secure it by pushing down gently, ensuring the little feet engage properly to lock it in place.

---

Secure the Bottom Case with Pentalobe Screws

• Use the Pentalobe screwdriver to secure the screws back into place.
• Start with the shortest screws for the front and sides, followed by the longer ones for the top.
• Tighten all screws carefully to avoid damaging the threads.

---

Test the New Battery

• Once the MacBook is reassembled, plug in the charger and turn it on.
• Ensure the battery is charging properly and the percentage is accurately displayed.
