Paso 1 Logic Board  ¶ 

Close your PowerBook, minding any cables that may interfere, and flip it over.

Paso 1 Logic Board  ¶ 

  • Close your PowerBook, minding any cables that may interfere, and flip it over.

  • Disconnect the power cable connector by pulling it straight away from its socket on the logic board.

Paso 2  ¶ 

Disconnect the battery cable connector straight away from its socket on the logic board.

Paso 2  ¶ 

  • Disconnect the battery cable connector straight away from its socket on the logic board.

Paso 3  ¶ 

Use the flat end of a spudger to pry the AirPort/Bluetooth cable connector up off the logic board.

Paso 3  ¶ 

  • Use the flat end of a spudger to pry the AirPort/Bluetooth cable connector up off the logic board.

Paso 4  ¶ 

Turn the PowerBook back over.

Paso 4  ¶ 

  • Turn the PowerBook back over.

  • Use the flat end of a spudger to pry the modem cable connector up off the logic board.

Paso 5  ¶ 

Use the flat end of a spudger to pry the PC card cage cable connector up off the logic board.

Paso 5  ¶ 

  • Use the flat end of a spudger to pry the PC card cage cable connector up off the logic board.

Paso 6  ¶ 

Disconnect both of the following connectors from the logic board:

Paso 6  ¶ 

  • Disconnect both of the following connectors from the logic board:

  • Left fan cable.

  • Inverter cable.

  • Be sure to pull only parallel to the face of the logic board, as pulling up on the socket will break it off the logic board.

  • When pulling these connectors away from their sockets, it is helpful to use your fingernails to pull on the ears at each side of the connector.

Paso 7  ¶ 

Remove the following four screws securing the optical drive to the lower case: Three 6.8 mm T8 Torx.

Paso 7  ¶ 

  • Remove the following four screws securing the optical drive to the lower case:

  • Three 6.8 mm T8 Torx.

  • One 3.8 mm T8 Torx.

  • Lift the optical drive out of the lower case, minding any cables that may get caught.

Paso 8  ¶ 

If necessary, remove the piece of tape securing the display data cable to the logic board.

Paso 8  ¶ 

  • If necessary, remove the piece of tape securing the display data cable to the logic board.

Paso 9  ¶ 

Pull the display data cable away from its socket to disconnect it from the logic board.

Paso 9  ¶ 

  • Pull the display data cable away from its socket to disconnect it from the logic board.

  • Be sure to pull only parallel to the face of the logic board, as pulling up on the socket will break it off the logic board.

Paso 10  ¶ 

Disconnect the right fan by pulling its connector away from the socket on the logic board.

Paso 10  ¶ 

  • Disconnect the right fan by pulling its connector away from the socket on the logic board.

  • When pulling this connector away from its socket, it is helpful to use your fingernails to pull on the ears at each side of the connector.

  • Be sure to pull only parallel to the face of the logic board, as pulling up on the socket will break it off the logic board.

Paso 11  ¶ 

Remove the following 12 screws:

Paso 11  ¶ 

  • Remove the following 12 screws:

  • Three black 5.7 mm T8 Torx.

  • Three 7 mm T8 Torx with spring washers.

  • Three 6.8 mm T8 Torx.

  • Three 3.8 mm T8 Torx.

Paso 12  ¶ 

If necessary, use a spudger to pry up the left edge of the logic board to separate the solidified thermal paste from the heat sink.

Paso 12  ¶ 

  • If necessary, use a spudger to pry up the left edge of the logic board to separate the solidified thermal paste from the heat sink.

  • If any resistance is felt when prying up on the logic board, we recommend softening the thermal paste by heating the board with a hair dryer before prying further.

Paso 13  ¶ 

Lift the logic board from its left edge and rotate it toward the right side of the lower case. The logic board on this model has a tendency to get caught on the lower case near the DVI port at the upper right corner. If it catches as you are rotating it, stop to avoid bending and breaking the logic board.

Paso 13  ¶ 

  • Lift the logic board from its left edge and rotate it toward the right side of the lower case.

  • The logic board on this model has a tendency to get caught on the lower case near the DVI port at the upper right corner. If it catches as you are rotating it, stop to avoid bending and breaking the logic board.

  • Rotate the logic board until it is nearly vertical, and wiggle it around until it releases from the lower case.

  • When reinstalling your logic board, be sure to apply thermal paste to the CPU. Our thermal paste guide makes it easy.

  • Only replace the gray thermal paste on the CPU. The white thermal material on the GPU chips can be reused.
