Einleitung

Hier wird der Austausch des unteren Gehäuses gezeigt.

  1. Entferne die folgenden zehn Schrauben, die den Boden des Gehäuses befestigen:
    • Entferne die folgenden zehn Schrauben, die den Boden des Gehäuses befestigen:

    • Zwei 2,3 mm Pentalobe Schrauben

    • Acht 3,0 Pentalobe Schrauben

    For all the screws you use the P5 pentalobe screwdriver?

    Carlos - Antwort

    Pentalobe is only for the screws on the bottom cover. The Torx screw driver is for the remainder.

    Fredrik -

    Is the Pentalobe screwdriver mentioned in the tools list? I did not have one so I used a filed down flat blade screwdriver. Not a fantastic idea, but it works.

    Alex Birkett - Antwort

    Yes, it's mentioned on the top of this page. P5 Pentalobe to be precise. I didn't have one either, so I bought one from iFixit and that works fantastic. An absolutely precise fit, which is important especially when you might open your MacBook a couple of times during the years you own it. Not using the correct tool might do more harm to the screws than you want! I once had this with a Lenovo Yoga 3 Pro, which has Torx screws (T4 I think) and I used cheap Chinese quality tools, with the result that both the tool and one of the screws are damaged.

    the macbook in the picture is 2012. does it has the same structure as 2013?

    Edison - Antwort

    I never, ever, ever considered using anything but the correct tool on the Pentalobe screws. Too easy to strip and void your warranty (if still in effect), as well as make it almost impossible to get inside later for another upgrade or repair. The Wiha P5 Pentalobe screwdriver fits like a glove and costs only about $11 (a fraction of your drive's price)at Amazon.com. Get it!

    is P5 supposed to be for all 10 screws? it works on the 2x 2.3mm at the top, but not for the 8x others for me. what size screwdriver for the 3mm? thanks

    monsieurescargot - Antwort

    Yes, the p5 works for all 10 pentalobe screw heads for bottom cover. The the different size mm reference only refers to the difference in length of the screws, but again both heads are p5.

    I followed this exactly and was able to replace my broken trackpad. I did not have to replace the ribbon OR the battery. However I would suggest getting the ribbon since it’s fairly cheap, as for the batteries I was able to do it with a card only. I didn’t use any heat or the liquid but it takes some time. You really have to work the card in there to release the glue. Also you must be very careful not to bend the batteries or damage them, if you do you must replace with new. This took me about 1.5hrs and my computer works like new. Apple cost for this job was around $450, I did it for $120. Big ups to ifixit for this awesome tutorial, tool set and parts!

    On a side note, only use quality tools, the cheap ones will break or strip the screws.

    Dustin Steward - Antwort

    Note that the eight 3mm screws have a shoulder under the head, while the two 2.3mm screws are “full thread”, i.e., there is no shoulder under their heads. It’s important to put the two screws with no shoulder at the hinge of the cover.

    All ten screws require a P5 Pentalobe screwdriver, preferably with a magnetized tip to help hold and position the screw.

    All of the screws have blue “Loctite” thread locker compound on their threads. This is to help prevent the screws from working loose and falling out. Don’t attempt to clean the Loctite from the screws — leave it in place, and it will continue to help prevent the re-inserted screws from working loose.

    When replacing the bottom cover, it is a good technique to insert and BEGIN tightening all ten screws BEFORE fully tightening any one screw. After all the screws have been started, then go around and finish tightening all of them. By doing this, you make it easier to feel that each screw has been started properly, and is not “cross-threaded”.

    This is what I found on my MBP mid-2014 13” Retina. All 10 used the same screwdriver. I didn’t see the blue “loctite” but I also got my computer refurbished.

    Evan Shulman -

    A good technique for starting to thread the screws when replacing them is to position and align the screw, and with the driver, gently turn the screw in the REMOVAL direction until you feel and hear a slight click. This click happens when the leading thread of the screw drops off of the leading edge of the thread in the hole — this is the point at which the threads are properly positioned for engagement. You can now turn the driver and screw in the TIGHTENING direction. This technique will help prevent accidental “cross-threading” of the screw, which will damage the threads permanently.

    Note that this is a useful technique when installing ANY threaded fastener.

  2. Gehe mit deinen Fingern zwischen das obere und das untere Gehäuse.
    • Gehe mit deinen Fingern zwischen das obere und das untere Gehäuse.

    • Hebe die untere Gehäuseabdeckung vorsichtig vom Gerät ab.

    This takes a bit more effort than you might expect. Put your fingers where shown and lift about 3inches. With enough upwards pressure the plastic holders will “pop free” and the bottom will come off easily.

    hamiltont - Antwort

    Agreed. A decent amount of force is required here.

  3. Der Gehäuseboden ist durch zwei Steckverbindungen in dessen Mitte mit dem Gerät verbunden. Drücke während des Zusammenbauens vorsichtig auf die Mitte des Gehäusebodens, um die Steckverbindungen wiederherzustellen.

    There are two screws that are shorter-they go to the back near the vent.

    wrbandllm - Antwort

    This was already mentioned at the start, it says 2x 2.3mm screws and those are coloured red instead of orange for the other ones in iFixit's image.

    addvariety - Antwort

    What is the black vinyl-y sticker on the inside of the case (some sort of shield?). I was forced to slightly puncture it in order to replace the feet on my laptop. Thanks in advance.

    Tommy Huang - Antwort

    When I got the back off, I found this piece loose, any idea what it is? about 9mm long frosted plastic

    This wording I found quite confusing. They just mean when putting the lid back on that you just removed in the previous step, push here.

    Mmm ttt - Antwort

    I took my pointer and thumb (which are luckily long enough) to feel where the studs are on the back panel, and then as I put the back panel back on, I pushed in the spot I had marked with my fingers to ensure I was applying pressure only on this part.

Do i have to hear some "click" noise when reconnecting the plastic clips? I did gently push the middle of the lower case, but the clips did not reconnected (it was still easy to remove the lower case). Hence i just put screws back, and then little bit strongly push the lower case again, but there was no "click" noise eithe ... However, the bottom case is completely flat, so i suppose it is ok...
