    • Remove the eight 4 mm Phillips screws securing the lower case to the MacBook.

    According to this page, the 8 screws are not identical.

    Can anybody tell me where each kind of screw is supposed to go?

    Gregoire - Contestar

    They are all 100% Identical. You were probably looking at a different model, or Apple has entered the wrong information... Hey, It happens...

    The screws on the Late 2009 are identical. The blue lock compound might make tightening some require a little more effort.

    hi, i just got back from the apple store and they are really keen for me to upgrade to a new laptop since my battery is old and the screen is cracked, so glad i found ifixit i would love to upgrade this puppy! gonna make it a real sleeper! styler hall wrote about sticking 16 gb of ram in his a 1342 ? is this a simply mather of ordering 3 4gb sticks ?aslo i currently have 4 gb and would like to upgrade to 8 ( or indeed 16) does that mean i need to buy all new sticks or can i continue to use the old one and stick a new one next to it ?

    thanks again mick van aar, perth western aus.

    michelvanaar - Contestar

    The A1342 will take up to 16 GB of RAM, however, there are only two RAM slots, so use two 8-GB RAM modules. Other World Computing (OWC) is a great reference source for info on exactly which RAM to use with which model; prices are usually much better on EBay though. Add an SSD from OWC and your machine will really scream!

    I hope that helps!

    Gregoire is right. The 8 screws are absolutely NOT identical, I’m looking at them right now, weeowey weeowey.

  2. The lower case is constructed of rubber-coated aluminum. Do not excessively bend the aluminum during removal, as any permanent deformation will cause tolerance issues after reassembly.
    • The lower case is constructed of rubber-coated aluminum. Do not excessively bend the aluminum during removal, as any permanent deformation will cause tolerance issues after reassembly.

    • Slightly lift the lower case near the vent opening.

    • Continue running your fingers between the lower and upper cases until the upper case pops off its retaining clips.

    • The location of these three clips is shown in the third picture.

    Do the retaining clips have to be re-engaged when replacing the lower case?

    John Morley - Contestar

    Answering my own question, the clips re-engage when the lower case is correctly positioned. You can help them by gently pressing the lower case with your thumbs midway along the two short sides. When everything is correctly aligned the eight screw holes line up.

    John Morley -

    Rather than running your fingernail down the sides to free up the retaining clips, I found that using an old credit card, inserted about 1/4”, to run along the left and right side popped those end retaining clips right off with no problem. You may need to twist the card slightly when in the middle area to help pop those off.

    • For precautionary purposes, we advise that you disconnect the battery connector from the logic board to avoid any electrical discharge. This step is optional and is not required.

    • Use the flat end of a spudger to lift the battery connector up out of its socket on the logic board.

    • It may be easier to use your fingernails to lift up on both sides of the connector.

    you do not need to remove the battery when replacing the hard drive or ram

    brilldoctor - Contestar

    beware not to lift the connector to close of the angle, as the picture suggest it. It might broke the angle. Attack by the middle.

    naamol - Contestar

    Not necessary?

    hikkymemo - Contestar

    Be careful of the corner of the battery cable connector when trying to pry it off with the spudge. I knocked the corner of mine. No operational impact but was not very pleasing!

    jljordanweb - Contestar

    Not necessary, but a good idea, so as to avoid any spurious charges going through the boards...

    svenaustx - Contestar

    @Svenaustx - What could happen if not removing this battery? Worst case? Not a geek on this but did change RAM on my Macbook Pro "15. Can't remember disconneting the battery back then. Shouldn't it be sufficient shutting the Mac off and ensure it has been used for an hour or so before replacing RAM?

    Good tip, thanks! I skipped ahead to step 17 and had no problem getting the magsafe board out from under the logic board and the new one installed. Saves a lot of work disconnecting connectors indicated as Fragile!

    matt15 -

    Thank You! Saved me an hour or so of work and a lot of stress!

    15sweyandt -

    I also did Step 6, then skipped to Step 17 & 18. Once I had the display data cable off, I could remove the 2 T6 Torx screws holding the MagSafe board on and remove it. You can reach under the logic board with the point of the spudger to work the cable out of the socket. Note how you maneuver the board out of the tight space so you can maneuver it back in. When you put the new MagSafe board in, plug in the cable first. If you bend the wires so the plug approaches the socket at the appropriate angle, you can nudge it in with the pointed end of the spudger.

    Thanks a lot for this hint! You saved my macbook, when I failed to unscrew the fan because of one completely destroyed screw. Thanks to your comment I skipped steps 7-16 and went straight to replacing the magsafe board without problems. The spudger and some 3D imagination and done,

    Sebastian M -

    • Use the flat end of a spudger to pry the AirPort/Bluetooth ribbon cable up off the logic board.

    The steps from 7 up to 16, and then 19 and 20 are not necessary. It looks like Apple intentionally designed the shape in the corner around the magsafe connector, so that it can be replaced without disconnecting and unmounting the main board. Also, the placement of the two screws mounting the magsafe board confirms that - they are easily available. This is true at least for the 2009 model, which I've successfully repaired.

    So you can skip the risky steps of disconnecting of all the main board connectors and go straight to unscrewing the magsafe connector. Then, having the spudger and some 3D imagination, you can remove the magsafe board with some 3D rotations. Same for mounting the new magsafe.

    I've found out that crucial simplification only because I failed to unscrew the fan (broken a screw completely, while following this guide step by step). Then I found a comment from user grze under step 6, which saved my macbook by confirming, that 7 to 16 can be skipped.

    • Use a spudger to pry the fan connector straight 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.

    Since this kind of connector and very fragile and easy to damage even with a spudger I use a needle that I insert in the front side of the connector, between the connector and the socket and only apply a little pressure while lifting up the needle. The connector will then pop up from one side. Repeat the procedure for the other side. With this method it's impossible to damage the connector. I adopted this method after ruining two or three connectors using the spudger.

    lemerise - Contestar

    Hi, how do you fix the axial which connects the fan with logic's broken! Thanks in advance..

    Gagandeep -

    HELP! Both the connector AND socket detached from the logic board! Is it possible (barring micro-surgery) to reattach the socket to the logic board?

    John Watson - Contestar

    same problem here...any ideas? Did you fix it again, John?

    Ben Kn -

    I disconnected the connector and socket from the logic board because I wasn't being careful and wasn't using a spudger tool as was recommended. Luckily, a friend of mine that's handy with a soldering gun was able to individually solder each wire from the cooling fan's wire assembly back onto the soldering points on the logic board. It's really intricate, tricky, and risky...but at that point, what choice do you have? I verify it's possible to fix and my cooling fan is now running perfectly fine.

    Dan Barnhart - Contestar

    • Remove the following three screws securing the fan to the upper case:

      • One 7.1 mm Phillips screw.

      • Two 5 mm Phillips screws.

    • Lift the fan out of the upper case.

    Agregar Comentario

    • Carefully pry the delicate rear speaker connector up off the logic board. These small L/R speaker connectors are quite easily broken.

    • Use extreme caution; this connector is easily destroyed.

    While these connectors are very delicate, a new upper body case will have new connectors already installed. I slightly broke two connectors while removing them.

    Also, the connectors have a notch underneath (on the logic board) for the corner of the spudger to fit into. The hard part is that you cannot see the notches until the connectors are removed.

    Nations81 - Contestar

    Hi. Long time ago, I know but.... How did you fix them?

    I snapped mine off, can it be soldered back on?

    Sai G -

    I used pointed tip of one side of the tweezers from the ifixit Home Tech Toolkit. I found this thinner pointed tip better than a spudger for hitting that notch in the socket underneath the connectors. Since this is a metal tool, I pried very gently and I was working on a MacBook with the battery taken out entirely (early on as suggested in the video) and was also using an Anti-Static wrist strap. I found the spudger broke one of the connectors because it's relatively thick plastic, and put too much pressure under the cables before the tip could reach the plastic block of the connector. The pressure under the cable popped the wire contact right through the top of the plastic block connector. (it was OK this connector broke since I didn't need to reuse it--my replacement keyboard/upper case came with its own cables.)

    Because the tips of the tweezers are angled, I felt I had better control of the torque I was applying than if I used a jeweler's flathead screwdriver.

    kenhtanaka - Contestar

    i used a very sharp dental pick - a tool i've permanently "added" to my ifixit tool kit bag

    pprod - Contestar

    Using a needle/pin works well. I did what another person mentioned in Step 8. Pry up from the back corner with the tip of the needle. Be gentle. One side will pop up a tiny bit. Move to the other side and gently pry there. Mine popped out completely at that point.

    • Use your fingernail to flip up the locking flap on the ZIF socket for the keyboard ribbon cable.

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

    I had to remove the battery again to insert the keyboard ribbon cable. I just couldn't get the right angle and force otherwise.

    asciimo - Contestar

    When reassembling make sure this cable is really deep in it's socket. (Use some force with the spudger wedging it in between the cable and battery). If you don't, you won't be able to power up the board. I had 2 logicboards that I thought were dead, but it turned out the cable was not inserted enough. Jump starting them with the jump pads did nothing (with or without cable connected), but connecting the cable properly made the board come alive. Really check this!!

    You sir, just saved my day! Switching boards between two mac and I thought I broke the two at once... This should be documented on the manual!!

    Note: the 2009 and 2010 model differ here. On one the 3 point connector is left and 2 point is right, on the other one the 3 point connector is right and 2 point is left.

    I found this while installing several logicboards for A1342.

    Peterdk - Contestar

    @Peterdk, are the connectors exchangeable?

    I mean, would putting the 3 pin on the 3 pin, and the 2 pin on the 2 pin, regardless of the position (left or right) be ok?

    Have you successfully used a 2010 logic board on a 2009 case?

    • Grab the plastic pull tab secured to the display data cable lock and rotate it toward the DC-In side of the computer.

    Just lift the tab up slightly to release the clip that secures the data display cable. Then the cable will slide out easily.

    matt15 - Contestar

    If the video data cable has been disconnected before, the adhesive on the might not hold. Be extra cautious in disconnecting this. An illuminated magnifier would be a good help on this step as it is very delicate. This was where I feared I would fail. Was very relieved in getting through this step...

    svenaustx - Contestar

    I wasn't careful enough here, and didn't realize that the silver metal piece around the connector is actually a locking clip. No wonder disconnecting the cable required more than a gentle pull. The clip popped out of the cable-side connector in the process, and was bent; fortunately I was able to very carefully bend the clip out just enough to get it re-seated in the connector; there are tiny slots on the sides of the connector that the clip fits into.

    kmcrawford111 - Contestar

    • Gently pull the display data cable connector away from its socket on the logic board.

    • Pull the socket parallel to the face of the logic board.

    • The display data cable socket is made of very thin metal and is easily bent. Be sure to pull the connector straight away from its socket.

    • Lift the side of the logic board opposite the ports out of the upper case.

    • Rotate the logic board away from the upper case until the ports clear the lip molded in the upper case.

    • Pull the logic board and MagSafe board away from the edge of the upper case as one piece.

    • The MagSafe board may get accidentally disconnected during this process. As a precaution, be sure the MagSafe board connector is securely seated in its socket before lowering the logic board back into the upper case.

    • Before lowering the logic board back into the upper case, be sure the left speaker and microphone cables are seated in their channels cut into the upper case (as seen in the third picture).

    (When re-installing) Before screwing down the logic board, go around the edge and make sure no cables are caught underneath, remember there are 11 of them, 12 if the battery is present at this point.

The computer fell on the MagSafe cable, wich pressed in the MagSafe board (socket) into the body so the cable and the socket couldn't reach contact. From this guide I only did steps 1 to 6 and 17 to 19(only the two screws for the MagSafe board). Then I could move the MagCharger board out enough so it could make contact with the charger cable. Then I tightened the two screws again. Allthou I was as carefull I could with the display data cable (step 17 -18) and looked on youtube allso, it did break a bit at the surrounding solder joint. But it's working. I didn't have to replace the MagCharger board, just move it back into position.
