MacBook Pro 14" 2021 Battery Connector Replacement

Difficulty

Moderate

Steps

Time Required

15 - 30 minutes

Introduction

Use this guide to disconnect the battery in your MacBook Pro 14" 2021.

This is a prerequisite-only guide! This guide is part of another procedure and is not meant to be used alone.

Tools

Step 1

Completely power off and unplug your MacBook Pro before you start. Close the screen and flip the entire laptop upside-down.
Use a P5 Pentalobe driver to remove eight screws securing the lower case:
Four 9.3 mm screws
Four 5 mm screws
Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your device.

Step 2

Press a suction handle into place near the front edge of the lower case, between the screw holes.
Pull up on the suction handle to create a small gap under the lower case.

Step 3

Insert an opening pick into the gap you just created.
Slide the opening pick around the nearest corner and then halfway up the side of the MacBook Pro.
This releases the first of the hidden clips securing the lower case. You should feel and hear the clip pop free.

Step 4

Repeat the previous step on the other side, using an opening pick to to release the second clip.

Step 5

Sliding clips along the back edge of the MacBook further secure the lower case. Separating these clips may require a lot of force—consider using gloves to protect your hands from the sharp edges of the lower case.
Firmly pull the lower case away from the back edge, one corner at a time, to disengage the sliding clips.
Keep the lower case flat to the MacBook. Don't pull upward until it's completely separated.

Step 6

Remove the lower case.
To reinstall the lower case:
Lay it down and align the sliding clips with the back edge of the MacBook. Press down on the lower case and slide it toward the back edge to engage the clips.
When one side is engaged, it may push the other out of alignment. Check both sides as you push.
Once the back corners of the lower case are secured and flush with the frame, press down along the middle of the lower case to engage the four remaining clips.
You'll hear and feel each clip snap into place.

Step 7

Peel back any tape covering the battery board data cable connector on the logic board.

Not strictly necessary to remove this end of the cable, as the other end is also disconnected later. However, it does get it out of the way.

Step 8

Use a spudger to gently pry up the locking flap on the ZIF connector for the battery board data cable.

Step 9

Disconnect the battery board data cable by sliding it out from its socket on the logic board.

Step 10

While your MacBook uses some Torx Plus screws, standard Torx bits work. Make sure to apply constant, downward force to avoid stripping.
Use a T3 Torx driver to remove the two 2.1 mm‑long 3IP Torx Plus screws securing the trackpad cable bracket to the logic board.

Sorry but this is not correct Apple procedure.

There is power running through the device still whilst you are unscrewing this plate/bracket and disconnecting the trackpad if you do it this way. This is why Apple put the small flex cable next to this, free to reach before touching anything else.

You must disconnect the battery flex cable next to the trackpad connector before you touch anything else.

Thanks

Is that not what steps 7-9 are doing? You cannot actually access the battery connector until you remove this cable as it's underneath. Which battery flex cable are you referring to?

Step 11

Use tweezers, or your fingers, to remove the trackpad cable bracket.

Step 12

Use the flat end of a spudger to pry up and disconnect the trackpad cable's press connector secured to the logic board.
To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Don't press down on the middle. If the connector is misaligned, the pins can bend, causing permanent damage.

Step 13

The trackpad cable is lightly adhered to the frame.
Peel the trackpad cable away from the device, making sure to separate the adhesive.

Step 14

Peel back any tape covering the battery board data cable connector under the large pancake screw.

Step 15

Use a spudger to gently pry up the locking flap on the ZIF connector for the battery board data cable.

Step 16

Disconnect the battery board data cable by sliding it out from its socket on the battery board.

Ich hab dieses Datenkabel zerstört. Ist das der Grund warum es nicht mehr lädt?
Welches Kabel bräuchte ich denn? Das hier Item # IF464-018-1?
MacBook Pro 14" (A2442, A2779) and 16" (2021 A2485) Battery Daughter Board Cable

Step 17

The battery board data cable is lightly adhered to the device.
Slide blunt nose tweezers under areas with adhesive to separate the cable from the device.
Remove the battery board data cable.

Removing is easy. We cant reinsert the battery data cable connector. It wont push in properly. Any helpful solution???

Step 18

Use a T5 Torx driver to remove the 3.8 mm 5IP Torx Plus wide-head screw securing the battery power connector.

Step 19

Use the flat end of your spudger to lift the battery connector away from the battery board, disconnecting the battery.
Lift the connector high enough that it doesn't accidentally make contact during the repair, but no more than 45 degrees to prevent damaging its hinge.
For added safety, place a barrier, such as a piece of a playing card, between the connector and board.

I would place a piece of card stock (business card) taped to the battery cells so the contact can’t be made.

Conclusion

To reassemble your device, follow these instructions in reverse order.
