STEPS:

Tools You Need

For this repair, you’ll need a variety of precision tools: T3 and T5 Torx screwdrivers, a suction cup, tweezers, spudgers (preferably a large flat-edge plastic one), 98% isopropyl alcohol, and an air duster. Adhesive strips or 3M replacement tape are also essential for speaker installation. All parts and tools used in this video are available via the links below or at tekdep.com.

---

Remove Bottom Case

• Power off the MacBook and flip it over.
• Use a P5 Pentalobe screwdriver to remove the six bottom case screws.
• Use a suction cup to lift the lower case until you can release the internal clips and remove it completely.

---

Disconnect Battery

• Remove the small cover shielding the battery flex cable.
• Disconnect the battery management flex cable.
• Using a T5 Torx screwdriver, remove the battery connector screw and gently lift the connector to isolate the battery.

---

(Optional) Remove Trackpad

• Using a T3 screwdriver, remove the retention plate holding the trackpad flex cable.
• Disconnect the flex cable and peel it off the battery.
• Switch to a T5 screwdriver to remove the screws holding the trackpad. They are located in groups of two around the perimeter and one in the center.
• Flip the MacBook over, carefully guide the flex cable through the opening, and remove the trackpad.
• Take care to collect and preserve the five small metal washers on the screw posts; they ensure the trackpad clicks properly.

---

Disconnect Battery Management Unit Flex Cable

• Fully disconnect the cable by removing it from both sides.

---

Detach Battery Daughterboard

• Use a T5 screwdriver to remove the center screw holding the battery daughterboard.

---

Soften Adhesive

• Apply 98% isopropyl alcohol around the edges of the battery cells and speaker units.
• Let it sit for several minutes to loosen the adhesive.

---

Begin Battery Removal

• Use a large, flat spudger to gently pry up the battery. Avoid sharp tools that could puncture cells.
• Note: The battery will not come out fully without tilting the logic board.

---

Prepare to Tilt Logic Board

• Disconnect the following:
  • Keyboard flex cable
  • Left and right speaker connectors
  • Additional small logic board connectors
• Use a T3 screwdriver to remove retention plates and T5/T3 drivers to remove board screws.
• Disconnect Wi-Fi antenna connectors.
• Carefully tilt the logic board upward slightly to allow battery removal. Do not over-bend or force it.

---

Remove Battery

• With the logic board tilted, slide the battery cells and connectors out from underneath.
• Remove any remaining adhesive strips with isopropyl alcohol and a scraper.

---

Remove Speakers

• Reapply isopropyl alcohol around the speakers to soften their adhesive.
• Use a spudger to pry out the left and right speakers. If you’re replacing blown speakers, you don’t need to be as cautious.
• Remove leftover adhesive with tweezers and clean the area thoroughly.

---

Clean the Fans and Inside

• Use tweezers to lift out heavy dust buildup from the fan fins.
• Blow out remaining dust using an air duster, especially in corners and vents.

---

Install New Speakers

• Apply 3M adhesive to the new OEM speakers if not pre-applied.
• Align based on bottom case screw point and top edge to ensure proper fit.
• Press into place and leave speaker connectors unplugged for now.

---

Install New Battery

• Remove protective film from the battery adhesive.
• Lift the logic board slightly and insert one side of the battery at a time, starting with the keyboard-side connectors.
• Press all battery cells into place firmly to ensure full adhesion.

---

Reconnect Components

• Plug in all previously disconnected cables, including:
  • Speakers
  • Logic board flexes
  • Wi-Fi connectors
  • Keyboard
• Replace all removed screws and retention plates using T3 and T5 drivers.

---

Reinstall Trackpad

• Verify washers are present on all five trackpad screw posts.
• Insert the trackpad and route its flex cable through.
• Reconnect the trackpad flex and secure it with its T3 retention plate.
• Use a cross-pattern to reinstall the T5 screws securing the trackpad.

---

Finalize Battery Connections

• Reconnect the battery connector and screw it down with the T5 screwdriver.
• Reinstall the battery management unit flex cable:
  • The small “S-turn” end goes to the battery daughterboard.
  • The end with the white dot connects to the logic board.

---

Test Before Reassembly

• Plug in the charger and power on the MacBook.
• Confirm:
  • Battery is charging
  • MacBook boots normally
  • Disconnect the charger to ensure the battery holds a charge
• If battery indicators are abnormal, check both ends of the battery management flex.

---

Reattach Bottom Case

• Click the case into place along all edges.
• Use the two longest screws for the upper left and right corners.
• Reinstall the remaining P5 screws.

---

TESTING & VERIFICATION

• MacBook powers on and recognizes new battery.
• Battery percentage is accurate and stable when unplugged.
• Both speakers produce clean, full audio with no distortion.
• Trackpad has correct tactile click and alignment.
