    • Whenever working near the logic board, it is always wise to first disconnect the battery to avoid short circuits.

    • If present, grab the plastic tab attached to the battery connector and pull it toward the front edge of the device. For Late-2011 models the battery connector will not have a tab and is simply a plug that inserts straight down into the motherboard--to remove pry the plug straight up.

    • If the plastic tab is missing, use a spudger to pry the connector up from its socket.

    • Pull the tab parallel to the face of the logic board.

    • Use the flat end of a spudger to lift the right fan connector out of its socket on 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.

  5. MacBook Pro 17" Unibody Logic Board Replacement: passo 5, imagem 1 %32
    • Remove the three 3.1 mm Phillips screws securing the right fan to the logic board.

    • In the Late 2011 MacBook Pro 17" Unibody these screws will be T6 Torx.

    • Lift the black plastic flap attached to the display data cable retainer and rotate it toward the DC-In side of the MacBook.

    • Pull the display data cable out of its socket.

    • The display data cable socket is very fragile. Do not lift the connector upward as you disconnect it, as the socket may break off the logic board. Pull the cable parallel to the face of the logic board.

  22. MacBook Pro 17" Unibody Logic Board Replacement: passo 22, imagem 1 %32
    • Remove the following eight screws securing the logic board and DC-In board to the upper case:

    • Six 3.2 mm Phillips screws

    • These may be T6 Torx screws on the Early 2011 model.

    • Release the tabs on each side of the RAM chip by simultaneously pushing each tab away from the RAM.

    • These tabs lock the chip in place and releasing them will cause the chip to "pop" up.

    • After the RAM chip has popped up, pull it straight out of its socket.

    • Repeat this process if a second RAM chip is installed.

    • Logic board remains.

This is a good guide if you are wanting to remove your trackpad on the A1297 mid-2010 model. There aren't many guides to do this, so this is a simple route to follow.

Do you know the fix por ethernet in Mac 2011 A1432?

ccsg259 - Responder

Good question! We’ve had good quality Ethernet cables easily slip out of the jacks on several of our MacBook Pros (and TiBook) over the years.
