    • 使用撬棒的尖端把扬声器电线拔出来。

    • 用手把右边扬声器电线往上提,把接口取出主板。

    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 - 回复

    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.

    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 - 回复

    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.

  3. 断开下面四条电线: AirPort/蓝牙电线
    • 断开下面四条电线:

    • 光驱电线

    • Trackpad 电线

    • 断开电线的时候,使用撬棒平头的一端,把接口从主板撬出来。

    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 - 回复

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

    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.

    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.

    The tape trick works. Since we’re in the middle of a home renovation project I used a piece of painters tape that was lying around. It doesn’t really stick to the cable but it just gives you that extra grip.

    domhnallk - 回复

    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.

    The tape trick was the only way it could go in for me.

    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.

    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.

    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 - 回复

    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.

    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.

    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.

    Not necessary to remove the small screw holding the silver colored retaining clip on the data cable retainer. (pictured still attached in the guide) Cost me 45 minutes trying to get it back on which included looking for, and fishing it out of, the places where it tried to hide because it’s so ding dang small it was tough to reattach and seemed to have a guided navigation system sending it everywhere but where it was supposed to go. Additionally, the middle hole on the retainer is empty in this step for reassembly as that is where one of the long rear cover screws goes when you put the case back together.

    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.

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 -

    The magnetic MagSafe connector pins have a grey plastic frame which can be seen as you look at it from the outside, looking inwards at the port. This plastic frame eventually starts to crack and break-up over the years. It’s not a necessary part so if your MagSafe connector has broken grey plastic on the external end of the connector, remove the pieces as they’re there only for cosmetic reasons.
