Throughout this repair, keep track of each screw  and make sure it goes back exactly where it came from to avoid damaging your device.

• Wedge your fingers between the upper case and the lower case.
• Gently pull the lower case away from the upper case to remove it.

If necessary, remove the plastic cover adhered to the battery contact board.

Use the flat end of a spudger to lift the battery connector straight up out of its socket on the logic board.

Be sure you lift up only on the connector itself, not the socket, or you risk permanent damage to the logic board.

Bend the battery connector up out of the way to prevent accidental contact with its socket during your repair.

• Remove the two 2.1 mm T5 Torx screws securing the logic board to the I/O board cable bracket.
• Remove the I/O board cable bracket.

Use the flat end of a spudger to pry the I/O board connector up from its socket on the logic board.

Be careful to only pry up on the I/O board cable, not the socket itself. This can damage the logic board.

Lift the end of the I/O board cable straight up on the logic board to bend it away from the socket.

To prevent damage to the cable, bend the end of the I/O board cable away from the socket.

Carefully place the tip of a spudger underneath the right speaker and pry it up from its socket on the logic board.

Carefully pry the right speaker up from the upper case.

Lift the right speaker at the end of its cable and pull it out of the case.

Insert the tip of a spudger under the left speaker cable near the connector and gently pry it up to free it from its socket on the logic board.

• Lift the left speaker up and around the battery to remove it from the upper case.
• Be careful not to snag the speaker cable on the side screw holes.

Use the flat end of a spudger to pry the trackpad connector up from its socket on the logic board.

• Pull the trackpad cable away from the battery adhesive tape.
• Be careful not to damage the cable. If it doesn't pull up easily, apply some heat with a heat gun or hair dryer to soften the adhesive and try again.
• If you are installing a new trackpad cable, make sure the new cable matches the shape of the old one. If you don't fold it over, the new cable will be too long.

• If necessary, peel off any tape covering the trackpad cable.
• Use the end of a spudger to unlock the slider on the ZIF connector.

• Pull the trackpad cable straight out of the ZIF socket on the trackpad control board.
• When reassembling, make sure the tab on the socket is in the upward, "unlocked" position before inserting the trackpad cable.

Remove the single 3.7 mm T5 Torx screw securing the battery board to the upper case.

• Apply a small amount of adhesive remover evenly around the edge of the rightmost battery cell.
• Wait 2-3 minutes for the adhesive remover to penetrate the adhesive at the bottom of the battery.

If you don't have adhesive remover, you will use a heat gun or hair dryer to warm and soften a portion of the adhesive securing the battery to the upper case, then carefully pry at that time.

• Push a plastic card between the right-most battery cell and the upper case to cut the adhesive between the two.
• Be careful not to damage any of the batteries with the tools during this process. Damaged lithium-ion batteries can leak dangerous chemicals and/or catch fire. Use only plastic pry tools
• If you encounter significant prying resistance, stop and reheat the section you are working on.

• Repeat in the adjacent battery cell.
• Place a small amount of liquid adhesive remover underneath the battery cell and wait 2-3 minutes for it to penetrate and soften the adhesive.
• Alternatively, you can reheat this section with an iOpener if needed.
• Push the plastic card in about an inch between the battery cell and the upper case and slowly pry the battery apart to separate all of the adhesive.

• Repeat the previous steps to separate the two left-most batteries.
• Remember to apply a small amount of adhesive remover under each battery cell and wait 2-3 minutes for it to penetrate and soften the adhesive.
• Use a second plastic card to separate the two left-most batteries from the upper case.

• Continue to repeat the prying steps.
• Insert a plastic card between the second left-most battery cell and the upper case to cut the adhesive bonding the two, and pry the battery away from the case.

• If using liquid adhesive remover, add a few drops of remover to the center of each of the two outermost cells.
• Lifting one side of the MacBook Pro by a few inches can help the adhesive remover flow in the correct direction under the battery. You can use a sturdy book or foam block to elevate one side of the MacBook Pro.
• Allow the adhesive remover to penetrate for 2-3 minutes before continuing.
• Gently fold the right-most battery cell and insert the plastic card correctly under the center battery cell.
• Push the card in about halfway through its length to cut the adhesive between the battery and the case.
• Avoid touching the trackpad and align the card where the adhesive is - on the logic board.
• Leave the card in place to prevent the adhesive from resealing.

• Repeat the same process on the remaining battery pack.
• Lift the outer battery cells and insert the plastic card about halfway into the left center battery cell, avoiding the trackpad.

• Return to the plastic card under the right center battery cell and twist it to separate the entire battery from the upper case.
• At this point, you have cut through the adhesive between the battery and the upper case, and the battery should come out easily.

Remove the battery

• Before installing the new battery, remove any remaining adhesive from the MacBook Pro case.
• If you're lucky, you can slowly peel the adhesive off with your hands.
• Otherwise, soak each section of adhesive with a bit of adhesive remover for 2-3 minutes, then scrape it off with an opening pick or other tool. This can take quite a bit of work, so be patient.
• Wipe off any remaining adhesive remover and give the MacBook Pro some time to air dry.
