Use this guide to replace the left speaker.

    • Remove the following ten screws securing the lower case to the upper case:

    • Two 2.3 mm P5 Pentalobe screws

    • Eight 3.0 mm P5 Pentalobe screws

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your device.

    If don’t have one of those neat project mats, then you can use small pieces of flattened blu-tack to hold the screws. If you arrange them in the shape of your mac book cover, and put the screws down methodically, you can get a one-to-one mapping of the screws to the correct screw holes.

    Or you can use an ice tray where you put the screws and the parts in separate bays in the same order as they come in the instructions.

    This is great! I used a small magnetic white board, and wrote on it to identify the parts as I went. This whole process, from the fast shipment to the great instructions to the complete, high quality, tool kit has been great. I’m typing this comment on my resurrected laptop. Thank you! Sue

    when doing this with metal tweezers as instructed in the video, it was difficult to get off and apparently while i was trying to do it, the tweezers went too far under and i believe made contact with the screw underneath? there was a zzz noise, an orange flicker and a little stream of smoke that came out. i freaked out and put everything back together to see if the laptop even still worked, it turned on and everything but died right away (i drained it before doing the repair anyway, so i was surprised it turned on at all).

    i finished the battery repair and did several other things while in there. i have charged it all the way as recommended and will use it later on to see how everything is, im hoping that it’s a okay, but could someone explain to me what happened and the possible consequences?

    • Remove the wide head 6.4 mm T6 Torx screw securing the battery connector to the logic board assembly.

    • Carefully lift the battery connector board up off the logic board.

    • It is recommended to bend the battery cables just slightly, to keep the board suspended up above the logic board and out of the way.

    • Do not fold the board completely over, or crease the cables, as this may damage the battery.

    • Grasp the Interposer with tweezers.

    • An interposer is the name for an interface that links one electrical connection to another. In this repair, it is the board connecting the battery to logic board.

    • Lift the Interposer off the logic board and remove it.

    • Removing this board will ensure that the battery remains disconnected throughout your repair, preventing your computer from accidentally powering on. It's also a good idea to take it out so it doesn't fall out unexpectedly.

    How can I remove interposer I m not able to remove it

    Raunak - crwdns2853112:0crwdne2853112:0

    you must lift it absolutely vertically, or it fouls against the locator pin in the corner- you can easily get the impression that it won’t come over the end of this pin- almost like it’s rivetted in. it isn’t. get a good grip on it with the tweezers in the centre hole & one of the sides, & lift it STRAIGHT up.

    • Use the flat end of a spudger to pry the headphone jack cable connector straight up off its socket on the logic board.

    • Gently bend the headphone jack cable to 90° up from the logic board.

    • Bending the headphone jack cable will allow you to disconnect the left speaker cable connector without having the headphone jack cable in the way.

    For an easier, lower-risk repair, skip this step and step 18 - go straight to step 19 and fold the speaker out of the way.

    Agreed, this is the way

    • Wedge the tip of a spudger beneath the left speaker cable connector.

    • Gently pry the left speaker cable connector up off from its socket on the logic board.

    • Be sure you are prying up on the connector, not the socket itself.

    It's easier to follow Step 19 & 20 first and then come to Step 18 (this step). Doing so will make it easier to remove that speaker connector easily holding the cable of speaker without having to use a pry tool.

  11. MacBook Pro 13" Retina Display Late 2012 Left Speaker Replacement: step 12, image 1 of 1
    • Use a T5 Torx driver to remove the following screws securing the left speaker to the upper case:

    • One black 6.8 mm screw

    • One silver 6.3 mm screw

    • One black 4.9 mm screw

    • The silver screw (in the corner) may be covered with a foam pad. If so, use your tweezers to peel it up and remove it.

    Be very careful on this step. If you aren’t you can snap the plastic on the corners where the screws go in. Remember to go slowly when spinning the screws back in, it doesn’t take gorilla torque to tighten them, just take it easy!

I accidentally pried up on the socket, which looks like it was soldered to the board. Left speaker doesn't work, of course. I assume there is no fix for this, other than replacing the board??

Thank you very much for the walkthrough. No problems to follow at all. Everything worked as a charm. Changed both speakers as per your other guide.

I was able to follow the steps exactly as described without damaging anything. Patience is the key.
