    A step is entirely missing here – removing the right speaker cable connection from the logic board and also removing the right speaker casing (all the pictures below show it already having been removed). You actually don't need to entirely remove the right speaker to get the logic board out but you will need to remove its screws and lift it slightly. And you will need to remove its plug from the motherboard but that's not hard and it looks identical to the left speaker plug/socket.

    Actually i didn't get why should i unstick the tape which gum up left speaker cable to the SATA data/power cable. It's gonna be hard to bond the tape again cause it looses the clue ability. I can definetely claim that there is no need to touch the tape.

    I too can say that there was no reason to remove the tape.

    Agreed. I completed the repair without removing the tape.

    Be careful and tender here, otherwise you risk that the connectors brake

    • Be careful not to snag the board on any of the rear case's screw posts.

    • The I/O boards at the bottom of the logic board will be the greatest challenge. It is recommended to pull gently to avoid any damage.

    If you have a helper (or if you're very coordinated and careful), you can very likely lift up the logic board far enough to replace both RAM modules without pulling the logic board all the way out. Just be careful what you touch, of course.

    This is the trickiest part of the whole operation. It took me a solid half hour to get the logic board out. I’m sure it would be easier a second time, because there’s not many delicate components around the USB/Internet sockets, so you can be a little more assertive with it than I felt comfortable doing.

  11. When installing the logic board, take care to align the exterior I/O ports correctly. The logic board can sit crooked even when secured with all its screws. Use a USB flash drive and/or ethernet cable to ensure the logic board is seated correctly while you screw it in.
