Introduzione

This guide will help you replace the logic board.

  1. Remove the following ten screws:
    • Remove the following ten screws:

    • Three 14.4 mm Phillips #00 screws

    • Three 3.5 mm Phillips #00 screws

    • Four 3.5 mm shouldered Phillips #00 screws

    • When replacing the small screws, align them perpendicular to the slight curvature of the case (they don't go straight down).

    How much weight can I save by removing the optical drive?

    gunes314 - Replica

    You can save a lot of weight if lets say your installing a solid state drive or putting in a second hard drive but if you know that you use the CD/DVD disc drive a lot then you might just want to leave the drive alone.

    Marshall WahlstromHelgren -

    Tip: Use one of those weekday pill holders to have a cheep way to store screws you remove and each day of the week can be for different sizes or parts. It has been handy to have (much less expensive than the magnetic mat.

    Robert Wacker - Replica

    Hello, where can I buy the screws I need in case I lose one of them?

    taylornya - Replica

    I have one stripped screw... How opening without drill it?! Any suggestions please?

    rodrigosady - Replica

    I also stripped a couple screws. I wasn’t able to open it up without drilling. After drilling the heads and removing the cover it was easy to hacksaw the tip and unscrew with a standard driver.

    Michael Wilkens -

    My top tip - make sure you buy good quality Phillips screwdrivers and a magnetic holder. Cheap screwdrivers won’t get the screws undone safely. Without a magnetic holder you have no chance of getting the tiny crews in and out safely.

    jeremyyoung - Replica

    A good Phillips 00 is your friend here. Also, when reinserting the screws, gently start anticlockwise and you wil feel a click at the start of the thread. This tells you you’re in the right place and less likely to cross-thread through force in the wrong place.

  2. Use your fingers to pry the lower case away from the body of the MacBook near the vent. Remove the lower case.
    • Use your fingers to pry the lower case away from the body of the MacBook near the vent.

    • Remove the lower case.

  3. Use the edge of a spudger to pry the battery connector upwards from its socket on the logic board. It is useful to pry upward on both short sides of the connector to "walk" it out of its socket. Be careful with the corners of the connectors, they can be easily broken off.

    Is this step of removing the battery connector required?

    manodh - Replica

    yes - as with disassembly of any electronic component you have to remove any power source. You don't want to accidentally turn the Mac on

    khull -

    Prying the battery connector off does not take much force. I did exactly what the guide suggested (walked it off back and forth) with the spudger without any problems. Just be very gentle, much like with anything inside laptops, they are very fragile and need to be worked with carefully. A+ instructions, battery replacement was a success.

    aekinaka - Replica

    Be patient on disconnecting this one. It worked for me step by step, little by little.

  4. Bend the battery cable slightly away from its socket on the logic board so it does not accidentally connect itself while you work.
    • Bend the battery cable slightly away from its socket on the logic board so it does not accidentally connect itself while you work.

    I put some tape between the connector and socket while working on the drive.

    Stephen Smith - Replica

    That's a good tip

    Anrothan -

    Great tip, I did that too

    Ahmed Mahran -

    One other note: The screw heads fit flush with the curvature of the case -- which means that they aren't exactly horizontal. In other words, they aren't perpendicular to the table that the computer is resting on. Don't try to force them straight in vertically, because you'll risk cross-threading them. (nearly ruined one screw hole myself!)

    lelandjordon - Replica

    On my MacBook Pro, the connector seems to be an integral part of the battery.

  5. Use the edge of a spudger to gently pry the fan connector up and out of its socket on the logic board. It is useful to twist the spudger axially from beneath the fan cable wires to release the connector. The fan socket and the fan connector can be seen in the second and third pictures. Be careful not to break the plastic fan socket off the logic board as you use your spudger to lift the fan connector straight up and out of its socket. The layout of the logic board shown in the second picture may look slightly different than your machine but the fan socket is the same.

    I successfully soldered the fan connector back on for a friend. I used a small soldering iron (maybe 6-10 watts) and ground the tip down to a very fine point. Also used a magnifying light and very fine rosin core solder. I took my time and lined everything up and was careful not to heat any other junction unnecessarily.

    Scott Stanley - Replica

    Yup. Be careful on this one. I was trying to gently pry up and popped it off the socket. Computer working fine after replacing magsafe board, but no fan for cooling…

    Thomas Carr - Replica

    This one is really delicate, as pointed out.  Be careful if using the pointed end of a spudger NOT to dig down and under ….there’s a layer of plastic-y insulation that can be torn.  I accidentally gored it with the pointy end of a spudger and it was slightly ripped.  Fortunately, I was able to press it down and there was no problem when the cable was reinserted.

    Carolyn Ryan - Replica

    For less than $16 I ordered a new fan from amazon. Fans eventually start making noise. If they fail, your system could expire from heat. Consider simply replacing your fan since this model is now about five years old. Here’s link:

    airshack - Replica

    I used a guitar pick and gently wiggled underneath to lift it up and out of the socket. no damage! woo hoo! on to step 7!

    jcundy2 - Replica

    I simply skipped this step and left fan wire connected to logic board. Just unscrew screws from Step 6, put fan on the logic board and remove whole stuff togheter.

    paczor - Replica

    Thanks, I did that too,,

    a lot easier

  6. Remove the following three screws securing the fan to the logic board:
    • Remove the following three screws securing the fan to the logic board:

    • One 7.2 mm T6 Torx screw

    • Two 5.3 mm T6 Torx screws

    These are T5 screws

    dbell316 - Replica

    I think so too, (maybe on a certain batch?) tried a T6 and its too big

    • Use the tip of a spudger to pull the right speaker/subwoofer cable out from under the retaining finger molded into the upper case.

    • Pull the right speaker/subwoofer cable upward to lift the connector out of its socket on the logic board.

    Reminder: When replacing the cable the connector should be placed in from above. This fooled me and I damaged the seat a bit, but not enough to prevent proper connection.

    Lee Hughart - Replica

    Excellent guide, I feel this bit could be clearer tho. As it is a socket like a fan connector.

    Mine had a foam pad on the top like the other lift-up connections and I’ve accidentally taken the socket off.

    So just to be aware if your mac has the foam pad on top of this connection.

    acupton86 - Replica

  9. Disconnect the camera cable from the logic board.
    • Disconnect the camera cable from the logic board.

    • Pull the cable parallel to the face of the logic board. Pulling the cable upward may damage the logic board or the cable itself.

    The camera cable head has bump at both sides. Just use two spudgers to pry it out.

    townbull - Replica

    thank you great suggestion

    Soham Thacker -

    Here's where the mid-2009 13" MacBook Pro 5,5 makes its first major departure from this guide. No such connection exists. At least nowhere I could find on the motherboard.

    Larry Horton - Replica

    IIRC the official service manual suggests putting the blunt or wide edge of a black-stick/spudger underneath the cable and then pressing down on said cable to provide better gripping force while pulling the cable out/away from the connector. It’s my tried-and-true method of choice.

    James - Replica

    Anyone has a data of this cable becausei brkoe it and i have an other same connector ??

    Mail : mr.leminecrafteur@gmail.com

    VARE - Replica

    Just broke this cable by pulling to hard. Definitely use a spudger to pry out the connector instead of pulling the cable.

    maxpoetter - Replica

    Same, any suggestion about its replacement?

    giovanni.billet - Replica

    Really grip those little bumps on the head with a pair of pliers and gently wiggle!

    moonsugar33 - Replica

    In case you need replacement parts for the broken cable : http://www.powerbookmedic.com/MacBook-Pr...

    To find out how to replace the cable, you can have a look at this tutorial : https://fr.ifixit.com/Tutoriel/Remplacem...

    Guillaume Lamaison - Replica

  10. Disconnect the following four cables: AirPort/Bluetooth cable
    • Disconnect the following four cables:

    • AirPort/Bluetooth cable

    • Optical drive cable

    • Hard drive cable

    • Trackpad cable

    • To disconnect the cables, use the flat end of a spudger to pry their connectors up from the sockets on the logic board.

    On the mid-2009 13" MacBook Pro 5,5 the Airport/Bluetooth cable is different from the other three cables in this step. It's fabric wrapped, and its connection works in a fashion more like the display data cable connection, although it does not have a lock that releases by pulling a tab back over the cable. So, to those of you who are repairing this model, be careful. Prying upward is not the way to remove this cable. I played with it until I could detect which parts were moving which way and why. Although I can't say with precision how the connection works, I removed it by gently coaxing slightly up at an angle and back along the plane of the optical drive. The idea is to pull the cable back out of its socket while lifting slightly.

    Too bad we can't post photos in the comments.

    Larry Horton - Replica

    Same with the Mid 2010 model - moving the cable parallel to the board, towards the optical device works fine.

  11. Use your fingernail to flip up the retaining flap on the keyboard ribbon cable ZIF socket. Be sure you are prying up on the hinged retaining flap, not the socket itself. Use the tip of a spudger to pull the keyboard ribbon cable out of its socket.
    • Use your fingernail to flip up the retaining flap on the keyboard ribbon cable ZIF socket.

    • Be sure you are prying up on the hinged retaining flap, not the socket itself.

    • Use the tip of a spudger to pull the keyboard ribbon cable out of its socket.

    • The cable may be difficult to insert. If you are having trouble, temporarily attach a piece of tape to the cable to help you guide the cable into the socket.

    Hello i've a late 2011 and have manged to break the keyboard ribbon cable ZIF socket. Is this a part that can be replaced? Ribbon is still good just the plastic has broken on the edge. Thanks

    Derek Cowan - Replica

    No, You'll need to replace the logic board. I'd probably just use a wired or bluetooth keyboard and put the money towards a new machine.

    maccentric -

    I ran into trouble reattaching the keyboard ribbon cable into the ZIF socket. I couldn't grasp it in a way that let me push it all the all back. A local repair guy told me his trick: use a piece of tape. Attach a piece of tape to the ribbon cable and make a tab so you can pull the cable into the socket. Use of a piece of tape that you can easily remove. Works like a charm.

    David - Replica

    Buy that man a pint! I've been working on computers professionally for a decade and I've never thought of that trick. Brilliant!

    Gryyphyn -

    Amazing this saved me!

    Felipe Cordero -

    You've saved me countless hours of crying trying to simply push it in

    Tunipguy -

    Thanks! This saved me hours!

    Marc Steffen -

    Thank you so much. Very clever idea that works like a charm!

    Todd Walls -

    Thank you so much! After 15 minutes of frustration, it inserted in less than 5 seconds.

    Todd Walls -

    After I put it all back together, the keyboard didn’t work; I traced it to this cable not being plugged in all the way. I used the tape trick to coax it all the way in to seat well and it works like a charm.

    Ruedi Schubarth - Replica

    Thanks for the tip about keyboard ribbon, saved me a major headache

    domhnallk - Replica

    It’s worth pointing out that the lever to lift this is at the back of the connector and that you’re pulling it towards yourself - this then releases the plastic on top of the cable that’s holding it in place.

    Nick Watts - Replica

    The tape tirck saved my bacon!! Thank YOU!

    Jonathan Davis - Replica

    Thanks so much. This trick saved the day!!!!

  12. If present, remove the small strip of black tape covering the keyboard backlight cable socket.
    • If present, remove the small strip of black tape covering the keyboard backlight cable socket.

    The bottom of the small strip has excellent adhesive which will re-stick upon reassembly without any problems. I handled the sticky side and even stuck it to a plastic tray without any issues. Which is to say the sticky-ness does not seem to wear off.

    airshack - Replica

    This is the most difficult ribbon cable to reinsert. As noted in the comments for the keyboard ribbon cable above I’d recommend also using a a small piece of tape to help reinsert.

    Bill Kirby - Replica

    I used Blu-Tac on the end of my spudger to provide a gentle grip to get it to slide in.

    • Use the tip of a spudger or your fingernail to flip up the retaining flap on the keyboard backlight ribbon cable ZIF socket.

    • Be sure you are prying up on the hinged retaining flap, not the socket itself.

    • Pull the keyboard backlight ribbon cable out of its socket.

    The first time I reassembled the system I left this tiny ribbon connector under the logic board by accident. If your keyboard backlight no longer works after reassembly it’s because you forgot to reattach this small connector. Fortunately, I caught my mistake before securing the logic board screws. It’s an easy to miss item.

  14. Use the flat end of a spudger to pry the sleep sensor/battery indicator connector up from its socket on the logic board.
    • Use the flat end of a spudger to pry the sleep sensor/battery indicator connector up from its socket on the logic board.

    the sleep sensor/battery indicator were not included with my new case, i had to transfer them over from my old case. once the battery is out (step 22), you can see the three screws you need to remove in order to take it out. it’s also secured by adhesive. the button for the battery indicator will likely fall out (at least it did on mine) when you remove the board, so be careful not to lose it…my new case did come with the button for the battery indicator (even though it didn’t come with the board or cable), but i just re-used the old one.

  15. Grab the plastic pull tab secured to the display data cable lock and rotate it toward the DC-In side of the computer. Pull the display data cable straight out of its socket on the logic board. Do not lift up on the display data cable, as its socket is very fragile. Pull the cable parallel to the face of the logic board.
    • Grab the plastic pull tab secured to the display data cable lock and rotate it toward the DC-In side of the computer.

    • Pull the display data cable straight out of its socket on the logic board.

    • Do not lift up on the display data cable, as its socket is very fragile. Pull the cable parallel to the face of the logic board.

    Its quite delicate, pull gently and it will pop out with a slight clicking sound

    Leo Jose - Replica

    On my mid-2009 13" MacBook Pro 5,5 the display data cable was square with the motherboard, rather than at an angle. I'm not experienced with working on computer connections, but if I were going to describe this procedure, it would be more like:

    "Grasp the plastic tab on the end of the display data cable connection, and pull it gently back over the cable, toward the DC-in board. The tab is connected to a flat rectangular 'ring' that locks the cable to its connection, and when you pull the tab, the rectangular lock will flip back over the cable, allowing the cable to be removed by pulling the same direction, parallel to the surface of the motherboard."

    Larry Horton - Replica

    Exactly the same as on the Mid2010 Model - never pull up, always parallel to the board, using the spudger to keep the cable down might helpfull while pulling with fingers the cable towards DC-In at the right side.

    Hans -

    My display is not working after reassemble the mac.

    Any reason?

    Nitin Sonwal - Replica

    I had the same problem, and it was solved by slightly unscrewing the 14.4 mm screw that sits nearest the ESC button (upper left hand side, if the computer is open as if you’re using it). All the way screwed in, and the display conks out (something must be getting pinched). Slightly loosened, and the display immediately came back!

    Shannon Maguire -

    I choose not to remove this, just laid the board over. Worked just fine.

    Justin Patterson - Replica

    I second this. It’s quite easy to leave this connection in place. The board flips over nicely, and everything is still accessible.

    Steven Weeks -

    I used my phone to photograph the entire underside of the Macbook Pro before I started removing things. This photo helped augment the excellent photos here. Take a few close-ups of each section/item before disassembly to reference upon assembly.

    airshack - Replica

    when reattaching the display cable, i used the spudger to tuck the spongy top flap underneath the cable lock, so that i could then get the cable lock down the entire way. i couldn’t get it under there (and get the lock closed) without it, the top part of the display cable blocked it.

    Matt - Replica

    When replaced the logic board when reassembled lap top screens not working. Saw others similar issues plugged in my monitor it’s working great must have messed up any ideas how to fix?

    Wayne McCarthy - Replica

  16. Remove the following nine screws:
    • Remove the following nine screws:

    • Five 3.6 mm T6 Torx screws

    • Two 4.3 mm T6 Torx screws

    • Two 7.2 mm T6 Torx screws

    • In some models the screws may be slightly shorter as follows:

    • Five 3.0 mm T6 screws

    • Two 3.6 mm T6 screws

    • Two 6.7 mm T6 screws

    2 of the 7 listed 4mm screws attaching the logic board are actually 4.5 or 5 mm.... unfortunately. I didn't notice that until I was reassembling. so I don't know which positions they came from.

    starf1970 - Replica

    I'm just noticing this too... I've put the longer screws as the two on the far left of the picture because they seemed to be the two holes I couldn't see the bottom to.

    ForumHermit -

    Just took one apart and paid attention this time. On this Mac, the screws colored orange should be red, and the 2 screws on the left side of the board should be orange (they’re a bit longer).

    maccentric -

    For keeping the screws straight I drew a simple diagram and placed them on it head down/threads up in their respective positions. Then all screws went back into their original positions without any guess work. Another suggestion I have during assembly is to start the screws without torquing them all the way down - leave them a little loose to allow some adjustment of the logic board for getting them all to line up with their holes, then torque them down. This technique also works for the screws on the bottom cover/lower case.

    Great guide! Saved me some dough, and now my MagSafe connector stays nice and cool.

    gregory mogle - Replica

    for me the two on the farthest left were the 4.3mm screws. otherwise all went as described

    Levi Hoover - Replica

    on something like this (like in iphones) i print the picture and place the screws on the picture. saves some problems and guessing.

  18. Use the tip of a spudger to gently peel the microphone off the adhesive securing it to the upper case.
    • Use the tip of a spudger to gently peel the microphone off the adhesive securing it to the upper case.

    Careful with this one. The wires are very thin fragile and it’s glued down very well making it extremely hard to remove. Just go slow and be patient otherwise you’ll damage the wires.

    Rob Kruit - Replica

    I finally got that mic out by gripping it between two spudgers like a pair of chopsticks and gently pulling it out at an angle. The rubber shroud on it makes the thing hard to grip, and when I finally pulled it free, part of the adhesive ring tore off and stayed stuck to the chassis. When reassembling the machine, I had to kind of squish it back into place. It doesn’t hold quite as well as it did before, but it seems fine.

    Thomas - Replica

    I managed to get the board out without prying the microphone off by twisting the board out while the microphone is still connected.

    You can then disconnect the microphone cable, which is a similar style connector to the fan cable and remove the board completely

  19. Minding the many connectors near its edges, lift the logic board from the end nearest the optical drive.
    • Minding the many connectors near its edges, lift the logic board from the end nearest the optical drive.

    • Without flexing the board, maneuver it out of the upper case, minding the flexible connection to the DC-In board that may get caught in the upper case.

    • Remove the logic board.

    I had the same issue. After wiggling the logic board back and forth and slowly applying more force, just up the threshold where I felt uncomfortable, it came out. The problem appeared to be caused by glue on the heatsink barcode sticking to the layer underneath.

    Shaun - Replica

    I did all this, and worked! .but Im wondering, has anybody unscrewed what seems to be a mini heatsink (black 1 inch square housing) on the integrated GPU? Could I re apply paste on that?

    I did make the change yesterday. inside it has a thermal pad, that appears to be 3mm or less. i try to clean on my best. I make a making a very tick pea size and added again. but i have no idea if it works or not. still having temps on 56c on idle. there is no much info on that. i use MX-4 from arctic. but i still, in my option, a little to for my use. if someone have more info on that part on the late 2011 i7 macbook pro 13inch please send the info.

    Carlos De Bernard -

    I did and applied Arctic Silver 5 underneath instead of the crap tape they put under there. This alone stopped the random freezing and rebooting problem I was having with this macbook pro. I recommend if you're already that deep into it, you might as well do it. I'm glad I did.

    ej257lgt -

    Need help. After I put everything back together, everything works fine but my macbook just wont charge. Any diagnosis on this? Anyone who can explain to me how the battery and the charging work in a Mac?

    justfinditjoshyip - Replica

    If this happened to me, I would first suspect I hadn't completely connected the DC-in board cable. If I hadn't just replaced the battery, I would wonder if the battery was good. MagSafe power cable connect connections fail too, especially if they've been attached for a long time to a red hot DC-in board.

    If those failed, I'd head to the genius bar!

    Larry Horton -

    I had this problem. I accidentally cut the a cable from the DC-in board and I had to buy this component and replace it. You have to be very careful when mounting back the logic board in its position to not get a cable from the DC-in board cut by the screws.

    Enrique Cerrillo Cuenca -

    I broke the black backlight shield.... be careful when you feel the logic board and the film underneath it seem stickinig togethre.

    • Carefully remove the heat sink from the processor.

    • If the heat sink seems to be stuck, it may be helpful to gently pry it off the processor with a plastic spudger. Be careful not to break any surface mount components on the processor while prying.

    • Be sure to clean off the old thermal paste and apply a new layer before you reinstall the heat sink. We have a guide that makes it easy.

    • Pull the RAM stick out of its socket.

    • Repeat this process to remove the second RAM chip.

    • Logic board remains.

    Reassembly is much easier if you take photos at each step prior to removing components. These extra photos augment the pictures you’ll find here. It’s always nice to see exactly how your system looked before you started messing with it! The top (edge by the screen) left and right corners get tricky unless you have close-ups of these areas for reference.

I decided to take out the logic board because I had a water problem. As you can problably guess all the componentes from both sides of the board, near the ventilation, were dirty with some green and white stuff so I cleand it all up with isopropilic alcohol. I assembeled it buck up and it turns on but it doesnt run the osx, screen doesnt turn on, you cant hear the welcome sound every time you turn on a mac and the only thing you can hear is the fan spinning faster and faster until it reaches its top speed and it stays like that. what can I do to fix it??

Three years later, the answer is that you need to reset your SMC.

is it possible to assemble the laptop completely without the unibody enclosure?

Grant Kendrick - Replica

Yes you can, but it would be unsafe for the macbook

Can I use this on my MBP 13 inch late 2011.

Does anyone know where can I buy the logic board?

Hi- Grateful if someone could please help me locate the SMC chip (U4900) and, if possible, the Thermal Sensor (T29) A1278 (2012) logic-board. My fan is constantly running flat-out (>6000RPM). Many thanks and a Merry xMas.

Thanks for this!

Yesterday I embarked upon replacing the keyboard in mine for the 2nd time, and ripped out one of the connectors! After pouring over schematics, the board layout, etc. this guide told me exactly what connector it was; the webcam! This means I won’t be replacing it, since I run Linux the webcam drivers would not work anyway. This saves me a massive headache, microsoldering (Louise Rossman style) and probably breaking more things.

THANK YOU! This guide helped me do a teardown remove the motherboard and do a isopropyl alcohol bath and ultrasonic cleaning. My girlfriends macbook was exposed to water and this gave me a chance to save it! It lives!

Can I replace the existing i5 2.3 Ghz logic board on MacBook Pro 2012 mid model to i7 logic board with 2.9 Ghz?

paw_sid - Replica

A friend of mine gave it to a dead macbook pro 13. So i don't know which model so try to look at back and it says A1247 and also i check the model number though apple and it says Mac book pro 13 inch mod 2012. So may question is the laptop not powering on but when i plugged the charger it's charging. How do i power using (power pads). Please help me…

Reassembled mac won’t power up. Please help. I had a lot of trouble with keyboard ribbon cable….might still not be in. Battery indicator lights showing battery power.

Hey guys,

Upgrading Early 2011 Macbook with this logicboard. Seen some comments and videos it should work.

From what I can see there is no heat sink included, so I will have to buy it separately.

But are there other componenets that need to be bought for this replacement? New speaker/microphone?

Or will I be able to reuse the other components?

I have previously upgraded with new HDD and the SSD/Dual Hard drive componenets.

Will the dual hard drive still work with this new board?

(The 2011 and the 2012 are both on the same “Compatible list” so I guess its already answered, but double checking)

thank you! i was able to use this as a guide to getting all the way to replacing the keyboard. (which is worth a guide in and of itself). and if anyone has tips on removing stripped screws (heads stripped) iʻd love to learn them. iʻve run into that problem on at least two MBPʻs (battery, and keyboard).

Kahana - Replica

Hello, wondering if I could take the next step to replace the RAM slot component? Do I need to remove the logic board for this? I can see the 4 screws that are easily visible (2 on either side of the ram slots). However, I don’t understand how it makes its electrical connection. Is this a soder job? or a snap connection? Thank you!

Hy guys,

My macbook pro mid 2012 unibody not turning on. No sign of power. Last night it was ok but in the morning next day its not turned on. I reset smc and do all things available on youtube and google. Dim green light blinking in magsafe. Without open it Authorised technician told me that your logic board is dead and its cost about $550. Please help me what could be probable cause of it. Battery was 80% charge when its working last night. What could be the fault battery or logic board or any other.

My MacBook won’t start up, it doesn’t even recognize the charger is attached. Logic board issue?

Changement fini. Passage du core i5 au core i7. Malheureusement, je n’ai pas acheté la carte mère chez ifixit (i7) parce qu’ils n’en avaient plus. Je l’ai payé 600 dollars au lieu des 300. Ifixit est un très bon site complet, et d’une grande aide.
