Mac mini Model A1176 Logic Board Replacement
简介
转到步骤 1This guide will show you how to replace the logic board.
-
-
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.
-
-
-
Gently bend the Jimmy outwards to pry the crack open a little larger and lift the lower housing up a small amount.
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.

-
Flip the Mac mini back over and lift the top housing off of the lower housing.
-
-
-
Slightly squeeze the two retaining arms toward each other and lift the AirPort antenna off its post.
-
-
-
Use the tip of a spudger to slightly lift the left side of the ZIF cable lock up from its socket.
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.
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?

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.
does any one know, where to get the connector from zhe ZIF Cable?
someone, that preowned my mac broke the holder!
Julian, did you ever find where to get a replacement lock for the Zip Cable. Mine is also broken..

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

Lift the audio board ribbon cable up out of its socket.
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.

Use a pair of tweezers to lift the hard drive thermal sensor cable connector up off its socket on the logic board.
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.
I agree Mike.

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.
-
-
-
Remove the Phillips screw near the audio ports securing the internal frame to the bottom case.
-
-
-
Gently lift the internal frame up from the bottom housing, minding the AirPort antenna and any other cables that may get caught.
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.
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.
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.

Firmly grasp the power button cable connector with a pair of tweezers and lift it straight up off the logic board.
-
-
-
Remove the single T10 torx lug securing the logic board to the bottom housing.
-
-
-
Gently lift the free end of the logic board and wiggle the board as you pull it away from the I/O ports.
Hi, when re-assembling, if you find resistance to the board sliding right up to the rear panel make sure that the spring finger on the casing goes over the power connector not inside it. It fits much better that way!

-
Push the PRAM battery toward the center of the logic board and pull it up out of its holder. You'll have to push the battery in further than you'd expect in order to get it to pop free.
-
When inserting the new battery, make sure the side with writing along the edges faces the black plastic holder. You should also ensure that the metal connectors make contact with the battery (you can bend them forward if they do not).

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

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”.

Despite mentioning recommended tools at the top I think it’s really worthwhile making a point about narrow Philips screwdrivers at this point before people start putting the case apart.
