Mac mini Model A1176 IR Board & Cable Replacement

Schritt 1

Power down your Mac mini, disconnect all of the cables, and flip it over.
Insert the Jimmy into the crack between the aluminum top housing and the plastic lower housing.
The Jimmy should reach a stop about 3/8" down.

A spackle knife makes these steps go much faster.

A double sided letter opener or a thin non-serrated butter knife will suffice.

To prenent cosmetic blemishes, place a matchbook cover or similar thin cardboard on the outer perimeter under the “jimmy”.

Schritt 2

Gently bend the Jimmy outwards to pry the crack open a little larger and lift the lower housing up a small amount.
There are several plastic clips on the lower housing that fit into a channel in the aluminum top housing. Your goal is to use the Jimmy to push these clips inward enough to free them from the channel, while gently pulling up on the lower housing.

Patience is your best friend.

Do not insert “jimmy in too far. Marking a line from tip upwards on the tool will prevent too far insertion, possibly breaking tabs or damaging internal components.

To prevent the cover closing back up, small strips of matchbook cover (os equivalent) can be inserted about half inch hold prevent closure.

Mike - 12/04/20

Schritt 3

Once you have the first side free, rotate the Mac mini and start prying up on the front edge.
Use the same prying motion to both bend the clips inward and lift the lower housing up out of the top housing.

Schritt 4

You may need to move the Jimmy along the edge to pry up all of the clips. Be patient and do a little bit at a time.

Schritt 5

Keep working around the perimeter, freeing the clips along the final edge.

Schritt 6

Flip the Mac mini back over and lift the top housing off of the lower housing.

Before reassembly, make sure no wires are sticking out.

Line up top cover carefully. Gently press down on top cover until top and bottom fully seated.

CAUTION! DO NOT PRESS TOO HARD ON THE COVER TO PREVENT CRACKING THE PLASTIC TOP.

GO EASY.

Schritt 7

Later in this guide you will remove several recessed Phillips screws. Bit drivers are generally too large to fit in the recesses, so be sure to have a thin shafted Phillips screwdriver on hand.
First remove the AirPort antenna (the larger of the two), located near the power button.
Slightly squeeze the two retaining arms toward each other and lift the AirPort antenna off its post.
Squeezing the two posts excessively will surely break them off the internal frame. Work delicately.
During reinstallation, you will have to slightly squeeze the two posts together so they fit into the openings on the AirPort antenna board.

Schritt 8

Use the tip of a spudger to slightly lift the left side of the ZIF cable lock up from its socket.
The ZIF cable lock will lift about 1 mm and stop. Do not try to completely remove the ZIF cable lock.

Now also lift the right side of the ZIF cable lock up from its socket.

chriZ -

Good catch of the incomplete unlocking instructions. ;P

Hmmm... what if I didn't read this before and I removed the cable and the lock sort of broke?... what would happen... would I experience problems? I can still put the cable back in place and push the lock back down with the spudger.

Dan O -

Same. I totally removed the lock , the edges are busted and won't stay in place, How can I get the cable to stay? what's the fix?

Suzanne -

Dan O & Suzanne, hold the cable in the socket and put a dab of hot glue on both sides, It's non-conductive and should hold...worked for me.

lamarhavard - 25/12/15

does any one know, where to get the connector from zhe ZIF Cable?

someone, that preowned my mac broke the holder!

julian gmeiner -

Julian, did you ever find where to get a replacement lock for the Zip Cable. Mine is also broken..

Suzanne -

This is not my first memory replacement in a Mini and I got over-confident and stupidly fully removed the audio cable ZIF lock and assumed I had broken something. But, now that I have read this guide more carefully, I am not sure. I sure would love to hear some detailed instructions for putting a ZIF lock back on.

Is it possible that I have removed it without having broken it? If I have broken it, do I have to buy a new cable? Just a new ZIF lock? A new audio board? This is a 2.0 GHz A1176.

Thanks!

GalvanicMacPro -

Michael, Mine seems to be broken. I bought & tried the Kapton Tape that was suggested & still no sound.

Suzanne -

C’est la première que je doit déverrouiller un câble ZIF. Je précise qu’il faut lever à gauche et à droite, ça force un peu, prendre appui sur le boitier du Mac, comme e montre la photo.

La partie noire reste dans la partie blanche (+1 mm), et la nappe flexible sort par le haut.

Ludovic - 17/12/17

Schritt 9

Lift the audio board ribbon cable up out of its socket.
If it refuses to lift from its socket, the ZIF cable lock is not fully released. Make sure it is evenly lifted about 1 mm from the socket on the interconnect board.

As an option to avoid potential damage when disconnecting the cable from the ZIF socket and clip, it is possible to unscrew the audio board and remove it along with the internal frame.

Schritt 10

Rotate the mini so that the SuperDrive slot loading mechanism is facing you.
Use a pair of tweezers to lift the hard drive thermal sensor cable connector up off its socket on the logic board.
Use tweezers to grab the connector (as seen in the picture), not the wires.
The connector is located under the optical drive opening, next to the PRAM battery.

Managed to leave this connected by flopping back the drive rather than totally removing

pglock -

WATCH OUT!!

separated one of the wires from the connector very easily. i would have preferred to use a spudger at this step. the tweezers in effect snipped the wire!!

mklsvg -

As my experience you should definitely use angeled tweezers as shown in several pictures. To avoid stripped cable deflash sharp edges of the tweezers a little bit. I never experienced problems when using that kind of tool carefully.

Timpetou -

I've had to remove a few of these connectors on iBooks and other small Apple devices ... I've found that, with careful and gentle pressure (working first one side and then the other) using a small flat-headed jeweller's screwdriver is best.

Mike Haines -

I agree Mike.

Note where the airport antennae connecting wire comes out from the interior along the top. When reassembling, it has to be routed the same way, or it won't reach its install position.

robert -

If your fan runs at high speed after you complete this project, you have forgotten to reconnect the thermal sensor.

Schritt 11

In the next few steps, you will remove the four Phillips screws securing the internal frame to the bottom case. Included in each step is an overview picture showing the general location and a closeup showing the actual screw.
Remove the recessed Phillips screw near the power button securing the internal frame to the bottom housing.

Schritt 12

Remove the recessed Phillips screw near the sleep light securing the internal frame to the bottom housing.
This screw is the longest of the four screws securing the internal frame to the bottom case.

Schritt 13

Remove the Phillips screw from the internal frame near the Bluetooth antenna.

Before removing any of these screws, there is another step needed which is not here:

On the front of the optical drive, right side as you look at the slot-load, is a small blue board attached by a single black screw. This needs to be removed before the optical drive can be taken out.

Mike Haines -

Schritt 14

Remove the Phillips screw near the audio ports securing the internal frame to the bottom case.

On reassembly, if you don't have a magnetic screwdriver, a tiny dab of grease at the tip of your screwdriver will help hold the screw on the driver so you can lower it into the recessed slot.

pfbloom -

Schritt 15

Gently lift the internal frame up from the bottom housing, minding the AirPort antenna and any other cables that may get caught.
It may be necessary to pull up near the interconnect board to separate it from the logic board.

At this point be careful that you don't pull out the Airport antenna ... but if you do, just check that it is back before re-assembling.

Mike Haines -

During re-assembly, the internal frame has to go in at an angle ... the back of the optical drive goes in first.

This means that you can seat the fan cover correctly, but more importantly, there is an interconnect board on the back of the optical drive that must be firmly pushed back into its housing on the logic board.

Mike Haines -

Reassembly: Before slipping the main frame back into its place, refer to earlier photos, ensuring proper routing of the WiFi cable.

Steve -

If, like me, you pull the wire on the airport antenna free, it snaps back into place easily. The connector is on the extra card screwed to the motherboard that looks like it has a phone battery embedded in it. The connector is at the top of the 'battery'. This accessory card is the wifi card, so it makes sense that the antenna plugs onto this.

Dan - 07/06/15

Schritt 16

The Bluetooth antenna is removed by simply lifting it up off the internal frame.
Remove the Bluetooth antenna from the internal frame by pushing up on both sides of the board as close to the center post as possible.
This may require a bit of force.

I tried using quite a bit of force and still this board would not come free. In the end I didn't remove it and found I could do the repair without removing it!

Mike Haines -

use tweezers at other side to clamp and push the whitestud trough, otherwise you might brake it

joost -

I left this piece in place and the optical drive wiggled around it. I applied as much force as I was comfortable with and I did not want to break the Blue Tooth antenna. This was a good work around and did not cause much if any trouble removing the old drive or placing the new drive into the computer.

sikkingj - 11/11/14

Comme le dit Mike, l’antenne est un peu dure à enlever. Elle peut être laisée en place, à l’étape 20, lever le lecteur par le coin opposé à la carte d’interconnexion, pour extraire le lecteur par l’avant.

Ludovic - 17/12/17

Schritt 17

Remove the two Phillips screws securing the optical drive to the internal frame.

A Phillips #0 is definitely required for this!

Javier Campos Delgado - 22/01/17

Schritt 18

Turn the mini 180 degrees and remove the two Phillips screws securing the optical drive to the internal frame on the other side.

Schritt 19

Remove the two Phillips screws securing the interconnect board to the optical drive.

Schritt 20

Use the flat end of a spudger to separate the interconnect board from the optical drive.

Schritt 21

Lift the optical drive out of the internal frame.

Schritt 22

Remove the single Phillips screw securing the IR board to the internal frame.

Schritt 23

De-route the IR board and cable through the channel near the hard drive in the internal frame.

Schritt 24

Flip the internal frame over.
De-route the IR board and cable through the channel within the internal frame.

Schritt 25

De-route the IR board and cable through the small plastic clip in the internal frame.

Schritt 26

Use your fingers to disconnect the IR cable connector from its socket on the interconnect board. Make sure to pull straight out, and to pull on the connector and not the cable.
