MacBook Pro 14" 2019 Charging Port Repair

Before starting this procedure, you must disable your Mac's '''Auto Boot''' feature. Auto Boot powers on your Mac when you open the lid, and may be accidentally triggered during disassembly. [https://www.ifixit.com/Guide/How+to+Disable+Auto+Boot/110034|Use this guide] or follow the abbreviated instructions below to disable Auto Boot. ''This command may not work on all Macs.''

Power on your Mac and launch '''Terminal'''.

Copy and paste the following command (or type it exactly) into Terminal:

'''sudo nvram AutoBoot=%00'''

Press '''[return]'''. If prompted, enter your administrator password and press '''[return]''' again. ''Note: Your return key may also be labeled ⏎ or "enter."''

You can now safely power down your Mac and open the bottom case, without it accidentally powering on.

When your repair is complete and your Mac is successfully reassembled, re-enable Auto Boot with the following command:

'''sudo nvram AutoBoot=%03'''

Before you proceed, unplug and power down your MacBook. Close the display and lay it on a soft surface, top-side down.

Use a P5 Pentalobe driver to remove the six screws securing the lower case:

Two 6.2 mm screws

Two 5.3 mm screws

Two 3.4 mm screws

Throughout this repair, [https://www.ifixit.com/Store/Tools/Magnetic-Project-Mat/IF145-167-4|keep track of each screw|new_window=true] and make sure it goes back exactly where it came from to avoid damaging your device.

Apply a suction handle to the lower case near the front-center area of the MacBook Pro.

Lift the suction handle to create a slight separation between the lower case and the chassis.

Insert one corner of an opening pick into the space between the lower case and the chassis.

Slide the opening pick around the nearest corner and halfway up the side of the case.

This releases the first of the hidden clips securing the lower case to the chassis. You should feel and hear the clip pop free.

Repeat the previous step on the opposite side, sliding your opening pick under the lower case and up the side to pop the second clip free.

Insert your opening pick once again under the front edge of the lower case, near one of the two centermost screw holes.

Give the pick a firm twist to pop free the third clip securing the lower case to the chassis.

Repeat this procedure near the other of the two centermost screw holes, popping the fourth clip free.

Pull the lower case firmly towards the front of the MacBook (away from the hinge area) to separate the last of the clips securing the lower case.

It may help to pull first at one corner, then the other.

Pull to the side—not up.

This may require a lot of force.

Remove the lower case.

To reinstall the lower case:

When the sliding clips are fully engaged and the lower case looks correctly aligned, press down firmly on the lower case to engage the four hidden clips underneath. You should feel and hear them snap into place.

Carefully peel up the large piece of tape covering the battery connector, on the edge of the logic board nearest the battery.

Remove the tape.

Gently peel back the small piece of tape covering the battery board data cable connector.

The tape is integrated into the ribbon cable and will not detach completely. Simply peel it back enough to access the connector.

Use the tip of a spudger to flip up the small black locking tab securing the cable in its connector.

Locking tabs on [link|https://www.ifixit.com/Guide/Recognizing+&+Disconnecting+Cable+Connectors/25629#s64969|ZIF connectors] are fragile, so be gentle when using the tip of the spudger.

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

Slide parallel to the logic board, in the direction of the cable.

Fold the battery board data cable back and out of the way.

If you're replacing your battery, you may need to completely remove and transfer this cable to your new battery. Disconnect both ends and carefully remove the cable. During installation, be careful not to install it upside-down or backwards—note the orientation in the photos.

Use a T5 Torx driver to remove the 3.7 mm pancake screw securing the battery power connector.

Use a spudger to gently lift the battery power connector, disconnecting the battery.

Lift the connector high enough so that it stays separated from its socket.

If it accidentally makes contact during the course of your repair, it could damage your MacBook Pro.

Use a T5 Torx driver to remove the two 1.9 mm screws securing the trackpad cable connector bracket.

Remove the trackpad cable connector bracket.

Use a spudger to disconnect the trackpad ribbon cable by gently prying its connector straight up from the logic board.

If you don't have an iOpener, use a hair dryer to warm up the cable instead. The cable should be warm, but not too hot to touch. Be careful not to overheat the battery.

Carefully peel the trackpad ribbon cable up off the battery, and push it out of the way.

Do not fold or tear the cable.

Use a T5 Torx driver to remove the ten screws securing the trackpad assembly:

Two 4.3 mm screws

Eight 5.8 mm screws

Remove the trackpad assembly.

You'll need to swing the display open slightly to remove the trackpad.

Take care to feed the trackpad ribbon cable through the MacBook Pro's frame without snagging.

Be sure not to lose the six small washers (two circular and four rectangular) resting on the underside of the trackpad.

Use a T5 Torx driver to remove the two 3.1 mm screws securing the battery board.

These screws lie under the battery board data cable. You may need to gently maneuver the cable from side to side to access each screw.

Either screw may have a water damage indicator sticker on the top. If so, remove it with a pair of [product|IF145-020|tweezers] and set it aside before removing the screw.

The battery board is permanently attached to the battery. Check to make sure it has adequate clearance to come out together with the battery, without snagging on other components.

Insert the flat edge of a spudger under the battery board on the side nearest the logic board.

Lift the battery board to an angle of about 45 degrees. If necessary, lift the battery power connector out of the way to give the battery board extra clearance.

The liquid adhesive remover provided in your kit can affect the antireflective coating on your MacBook Pro's display.

To protect your display, place a sheet of aluminum foil between the display and keyboard and leave it there while you work.

Additionally, layer an absorbent towel directly underneath the trackpad area to soak up any excess adhesive remover.

Now that your MacBook Pro is fully prepped, it's time to prep yourself.

iFixit adhesive remover contains acetone, a mild skin and eye irritant.

Wear eye protection when handling and applying the adhesive remover. (Eye protection is included in your kit.)

Do not wear contact lenses without eye protection.

Protective gloves are also included in your kit. If you are concerned about possible skin irritation, put your gloves on now.

Pull off the black rubber stopper from your bottle of adhesive remover.

Twist to loosen or remove the bottle cap before you cut the applicator tip.

This unseals the bottle and allows the pressure to equalize before you cut the applicator tip. '''If you skip this step, the adhesive remover may spray out unexpectedly when the tip is cut.'''

Use scissors to cut off the sealed tip of the applicator.

Cutting close to the narrow tip will give you better control so you can apply the adhesive remover in small amounts.

Twist and close the bottle cap securely before you proceed further.

Apply a few drops of adhesive remover underneath the front edge of the battery cell that lies nearest the fan.

You don't need to use very much. The small bottle contains more than twice the amount of solvent needed to remove all the battery cells.

Tip the front edge of your MacBook Pro up at a slight angle so that the liquid adhesive remover flows underneath the battery cell.

Wait 2-3 minutes before you proceed to the next step, in order to give the adhesive remover time to work.

After 2-3 minutes have passed, slide a [product|IF145-101|plastic card] under the edge of the battery cell where you applied the adhesive remover.

It may help to gently twist the card to open up a slight gap between the battery cell and the MacBook Pro's case.

Gently work the card deeper under the battery cell to break up the adhesive securing it in place.

This should not require much force—the adhesive remover does most of the work. If you aren't able to get your card under the battery cell, apply a bit more adhesive remover as instructed above and wait 2-3 minutes before trying again.

Twist the card to raise the battery cell until it fully separates from the aluminum case.

Don't try to remove the battery cell completely just yet—it's still attached to the remaining cells.

Leave the plastic card temporarily in place underneath the battery cell.

This prevents the cell from re-adhering to the case while you work on separating the remaining cells.

Repeat the previous six steps to separate the other outer battery cell, on the opposite side.

To separate the center battery cell, raise the back edge of the MacBook Pro and prop it up on a foam block or book, so that the adhesive remover will flow away from the logic board.

Apply a few drops of adhesive remover along the back edge of the battery cell.

To compensate, apply a few more drops of adhesive remover along each side of the center battery cell.

Wait 2-3 minutes before proceeding to the next step.

Slide a plastic card under one of the side edges of the center battery cell.

Try to keep your card well clear of the logic board as to not risk damaging fragile components.

It may help to gently twist the card to open up a slight gap between the battery cell and the MacBook Pro's case.

Use the card to lift the battery cell until it fully separates from the aluminum case.

Lift and remove the battery.

Before installing your new battery, remove all the old adhesive from the MacBook Pro's case.

With a little luck, you can slowly pull out each strip of adhesive with your fingers.

Otherwise, soak each strip of adhesive with a bit of adhesive remover for 2-3 minutes, and then scrape it out with a plastic tool. This can take quite a bit of work, so be patient.

Mop up any remaining adhesive remover and give your MacBook Pro a few minutes to air dry.

The replacement battery included in your iFixit kit comes with adhesive pre-installed. Test the battery's fit and alignment carefully before peeling off the film covering the adhesive, and then press each cell firmly into place. If any additional films/liners are present that weren't on your original battery, remove them now.
