Introdução

Use this guide to replace your bare logic board. This requires removal of every component attached to the logic board.

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

    • Three 13.5 mm (14.1 mm) Phillips screws.

    • Seven 3 mm Phillips screws.

    • When removing these screws, note how they come out at a slight angle. They must be reinstalled the same way.

  2. Using both hands, lift the lower case near the vent to pop it off two clips securing it to the upper case.
    • Using both hands, lift the lower case near the vent to pop it off two clips securing it to the upper case.

    • Remove the lower case and set it aside.

  3. For certain repairs (e.g. hard drive), disconnecting the battery connector is not necessary but it prevents any accidental shorting of electronics on the motherboard. If you do not disconnect the battery connector, please be careful as parts of the motherboard might be electrified. Use the edge of a spudger to pry the battery connector upwards from its socket on the logic board.

    • Use the edge of a spudger to pry the battery connector upwards from its socket on the logic board.

    • It is useful to pry upward on both short sides of the connector to "walk" it out of its socket.

  4. Bend the battery cable slightly away from its socket on the logic board so it does not accidentally connect itself while you work.
    • Bend the battery cable slightly away from its socket on the logic board so it does not accidentally connect itself while you work.

  5. Remove the two 7.4 mm Tri-point screws securing the battery to the upper case.
    • Remove the two 7.4 mm Tri-point screws securing the battery to the upper case.

  6. Carefully peel the battery warning label off the upper case between the battery and the optical drive to reveal an additional Tri-point screw.
    • Carefully peel the battery warning label off the upper case between the battery and the optical drive to reveal an additional Tri-point screw.

    • Remove the last 7.4 mm Y0 Tri-point screw securing the battery to the upper case.

    • Do not remove the label from the battery.

  7. Use the attached plastic pull tab to remove the battery from the upper case.
    • Use the attached plastic pull tab to remove the battery from the upper case.

    • If you're installing a new battery, you should calibrate it after installation:

    • Charge it to 100%, and then keep charging it for at least 2 more hours. Next, unplug and use it normally to drain the battery. When you see the low battery warning, save your work, and keep your laptop on until it goes to sleep due to low battery. Wait at least 5 hours, then charge your laptop uninterrupted to 100%.

    • If you notice any unusual behavior or problems after installing your new battery, you may need to reset your MacBook's SMC.

  8. Remove the three 3.4 mm T6 Torx screws securing the left fan to the logic board.
    • Remove the three 3.4 mm T6 Torx screws securing the left fan to the logic board.

    • In some models, these T6 Torx screws may be 3.1 mm long.

  9. Use the flat end of a spudger to disconnect the left fan connector from 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.

Does anyone ever respond to these post? Why come here for help if no is here to help?

Thank you Miroslav! My computer blew up last week and I felt all hope was lost until I found your guide. I used to repair laptops 10 years ago but never worked on a mac. this is exactly what I needed to see to know what to do!

Apple had a replacement service for late 2011 15inch MBPs which cured a mysterious fault which rendered it un-usable. I had mine fixed at a Genius Bar but my mate who also bought one has missed the program and has a completely dead MBP. Am I right in assuming that following your procedure above and using one of your logic boards would fix this?
