Mac Mini Mitte 2010 Logic Board austauschen

Schritt 1

Entferne folgende drei Torx Schrauben:
Eine 5,0 mm T8 oder 2 mm Inbus
Eine 16,2 mm T6 Schraube
Eine 26 mm T6 Abstandsschraube

In my case, the yellow circled standoff already came out with the previously removed fan.

My standoff screw was really tight and my T6 stripped the screw. :( But, because it's effectively just used as a post to stabilise the fan, I ended up using some surgical clamps, grabbing the standoff where the rubber grommet sits, and gently twisted the screw loose. No major damage because that part of the screw isn't really used! Just be careful and gently twist (patience is KEY) to loosen.

The weak design of the long standoff screw (not enough material around the star-patterned socket head) has probably caused damage of the internal head during production of the Mac Mini!

The standoff screw was in my case extremely tightened and the T6 Torx screw driver could not be used anymore (due to damage of the socket head after applying too much torque during the original assembly).

I needed to use a High Leverage Combination Plier in vertical position to loosen the screw without damage to other parts. I tried to keep the rotation axis of the screw at the centre of the flat nose of the plier. Minor scratches to the screw can not be avoided in this way.

Schritt 2

Ziehe die Drähte für die Festplatte und die Thermosensoren hoch, um die Stecker aus ihren Sockeln auf dem Logic Board zu lösen.

The thermal sensor is VERY delicate, hold the connector down with a spudger and lift the cable with some tweezers. Long list of people online who have accidentally removed the connector from the logic board because the solder is insufficient.

I second the comment about using something, say a small screwdriver, to carefully put some pressure on the connector whilst then prying the cable up.

Simon Martin -

Excellent advice - thanks. I used a small set of tweezers to gently lift up enough cable to hold onto, and then to hold the sockets onto the logic board whilst I pulled! Success!

Mike Haines - 27/07/16

Note: the clips lift straight up, although after they are removed, it appears that tiny "prongs" are in the remaining socket. What look like tiny prongs are just horizontal wires. To replace, push the clips straight down. I used metal picks (like fine bent ice picks - available at Harbor Freight) to get under the edge of the plastic clip and lift up. I pulled gently on the wires with tweezers as I pried up the clips, but I would not count on pulling alone to get the job done.

Steve Dollar - 02/10/16

Don’t have these, solid state drives?

Schritt 3

Löse die Stecker von Festplatte und optischem Laufwerk mit dem flachen Ende des Spudgers aus ihren Sockeln auf dem Logic Board.

The removal of the SATA connectors for the hard drive and the optical drive should probably be separated into two steps. It's easy to miss the second one and pull a SATA connector off.

Not confirming that I did it, but I am looking for someone to solder a SATA connector back on. ;)

Schritt 4

Um den Thermosensor am optischen Laufwerk zu lösen, musst du das Kabel zwischen Daumen und Spudger einklemmen, dann den Spudger nach oben ziehen. Dadurch hebt sich der Stecker aus seinem Sockel auf dem Logic Board.

These sensors are too fragile in some cases. In my case both the hard drive and optical sensor cables tore off despite all my best efforts. The plastic holding down the cables appears to be too fragile or brittle and simply tears as the cables are pulled away.

nirv - 02/04/15

Pulling the socket off the board seems to be a common problem. I am going to investigate making a tool to hold down the socket while prying up on the plug.

For the time being I am using an app that controls the fan speed by sampling other sensors, such as the CPU heat sink.

papa Hajek - 01/09/15

There are two problems with these connectors. First off they're made of very thin plastic so break easily (something addressed in later Mac mini's). Second the socket melts to the connector making it impossible to lift it.

If you do break it the metal tabs of the socket should we easily resoldered. Some practice beforehand, a fine tip solder iron, some leaded solder and your away.

Brent - 17/10/16

En mi caso perdi el sensor de la unidad optica y ahora el ventilador se mantiene acelerado y no se si para que vuelva a su velocidad normal habré de conseguir el sensor optico. (cuando hice las pruebas con el equipo abierto, mientras probaba otra unidad optica no me daba esa falla).

Monserrat Bojorges Flores - 03/03/17

Don’t see this connection, wires, only an empty connector.

chris warren - 30/03/21

When in doubt which of the two nearby sensors is the HD or the optical drive thermal sensor during assembly (!), look for instance at the guide to remove the hard drive. The two thermal sensors of the hard drive (see step 13 of this guide) are taped to the outside of the HD. The cable of the optical drive thermal sensor is below the HD (with the Mac mini upside down).

Schritt 5

Hebe den Verbinder des Infrarotsensors mit der Spudgerspitze aus seinem Sockel auf dem Logic Board.

Schritt 6

Zum Entfernen des Logic Boards müssen die beiden zylinderförmigen Stäbe des Mac Mini Logic Board Removal Tools in die mit Rot gekennzeichneten Löcher gesteckt werden. Die Platine kann zerstört werden, wenn Instrumente in irgendwelche anderen Löcher der Platine gesteckt werden (außer den Markierten).
Stecke das Mac Mini Logic Board Removal Tool in die zwei mit Rot gekennzeichneten Löcher. Vergewissere dich, dass die Stäbe das Gehäuse unter der Platine berühren, bevor du fortfährst.
Wenn du das Werkzeug nicht hast, kannst du es mit zwei Stiften mit maximal 2,5 mm Durchmesser probieren. Setze beide in die markierten Löcher ein.
Ziehe das Werkzeug vorsichtig in Richtung des I/O Boards. Dieses sollte nun zusammen mit der Platine langsam aus dem Gehäuse herausgeschoben werden.
Höre auf zu ziehen, wenn das I/O Board sichtbar vom Gehäuse getrennt ist. Entferne das Werkzeug.

I had a couple of 3/32" drill bits in my tool chest. Worked perfectly (2.38 mm)

Derek Shaw - 12/11/15

two fischertechnik screw drivers work perfectly as well!

Norbert Wagner - 04/09/19

Used 2 bigger paperclips. Straightened into single wire. Then in one of the previous bends I had bent it again and squeezed with pliers together so I have 2 "legs" of this improvised tool for better stiffness of wire. Went out nicely. It actually looks like a older hairpin, but more flattened...

But now I see there is a lot of paperclips on the market. Only the "smaller" ones I might use to bent it into 3 parts. So it depends of what is lying around.

Petr Sourek - 14/03/23

Schritt 7

Drücke die beiden Plastikclips ganz links und rechts am I/O Board gleichzeitig nach innen und ziehe das I/O Board aus dem Gehäuse.

I’ve popped the logic board out a little bit, but it won’t move any further. I can’t see what the clips are or how to work them.

Ben - 15/10/19

Look at step 20 below - you see one of these connectors on the side of the IO board, just under the fingers.

Aleks Gekht - 10/11/19

Schritt 8

Ziehe die ganze I/O und Logic Board Einheit so weit aus dem Gehäuse, dass du an den Stromanschluss kommst.
Löse den Stromanschluss mit einer Pinzette vom Logic Board.
Ziehe den Stecker des Stromanschlusses in Richtung der Öffnung des optischen Laufwerks.

Tweezers aren't strong enough. Use some small needle-nose pliers. Hold the I/O board and it pull away.

Tyrone Steele - 18/09/16

By the time you get to this step, the hard drive can be easily removed by simply sliding it out over the logic board. Then you can simply pull off the cable with your fingers. When re-assembling, again, attach the power cable connector first, with your fingers and slide the logic board all the way in. Then slide the hard drive in over the logic board.

Aleks Gekht - 10/11/19

I suggest to list this specific type of tweezers as shown in Step 19 at the beginning as useful/recommended tool to reconnect (!) the power cable. I could pry the power cable with the blunt side of a scalpel knife. But I sorely missed something like this tweezer when trying to reconnect the cable.
