The heat sink helps keep the processor cool and happy.

  1. Use a coin to turn the battery locking screw 90 degrees to the right.
    • Use a coin to turn the battery locking screw 90 degrees to the right.

    • Lift the battery out of the computer.

  2. Remove the four Phillips screws from the memory door.
    • Remove the four Phillips screws from the memory door.

    • Slide the memory door away from the memory compartment.

    • Remove the long black Phillips screw next to the memory card.

    • Remove the small EMI finger beneath the black screw.

    • On the keyboard, remove the F1, F2, F11, and F12 keys.

    • This is scary - take a deep breath before continuing. Place your index finger under the upper left corner of the key and lift up until you hear a click. Then, transfer your finger to the left edge of the key and lift up to pull the key off.

    • You're freeing the two tabs on the left of the key from the two small holes in the plastic scissors mechanism.

    • When replacing the keys in the keyboard, place the key directly over the slot where it will go and press down until you hear the key click into place.

    • Use your fingernail or a small flathead screwdriver to peel up the gray stickers covering each of the screws.

    • Remove the two short Phillips screws.

    • Lift the keyboard by the 'esc' and 'eject' keys and gently lift up until the keyboard is vertical.

    • Grasp the keyboard connector ribbon near the connector and disconnect it from the logic board.

    • Remove the three 2.5mm Phillips screws from within the battery compartment.

    • Turn the computer 90 degrees clockwise and remove the two Phillips screws from the casing.

    • Outside case screws are aprox. 1/4 in long

    • Turn the computer 90 degrees clockwise again, and remove only the bottom screw on either side of the hinge.

    • Turn the computer 90 degrees clockwise just one more time, and remove the two Phillips screws on the exterior wall of the battery compartment.

    • Note: For reassembly the two screws have long necks.

    • Turn the computer over and open it up.

    • Remove the following 14 screws:

      • Six 2.5 mm Phillips on either side of the keyboard area.

      • Five 4.5 mm Phillips on the left half of the keyboard area.

      • One 7 mm hex in the upper left corner of the upper case (a T6 Torx driver will do the job nicely).

      • One 15 mm Phillips in the upper middle of the keyboard area.

      • One 16.5 mm hex in the upper right of the upper case (again, a T6 Torx driver will work well).

    • This step is extremely tricky, and has the potential to ruin your computer. It is easy to pull the plug with the red and black leads (the power) out of the motherboard. If you do that, it is nearly impossible to fix.

    • Peel up the two pieces of foil tape on the left side of the keyboard area.

    • The connectors at the ends of the cables are attached very firmly to the sockets on the logic board. Pulling directly on the cable will either separate the cable from its connector or the socket from the logic board.

    • Carefully disconnect the microphone and power cables from the logic board. Using your fingernails or a dental pick, carefully pry the connectors from their sockets. Make sure you're pulling only on the connector and not on the socket.

    • Starting at one of the upper corners near the screen, work around the frame, separating the upper case from the lower case.

    • Using a screw driver, gently release the two grey plastic clips inside the battery compartment in order to remove the right part of the upper case.

    • There are two more grey plastic clips holding the left part of the upper case. They are not easy to release as they are hidden from view prior to disassembly. They are in the same position as the two in the battery compartment, but on the opposite side of the trackpad. Try to stick a flat pry tool into the clip holes and push the clips inward (toward to screen) so they disengage and release the left part of the upper case.

    • Lift the upper case off the computer.

    • Peel back the yellow tape securing the inverter cable near the fan.

    • Remove the following eight screws:

      • One 4.5 mm Phillips near the modem.

      • Three 6 mm Phillips near the display.

      • Two large 7.5 mm Phillips with attached springs.

      • Two 13 mm Phillips, one on the lower left side of the heat sink and one between the fan and the optical drive.

    • Peel up the Bluetooth cable on the right side of the fan.

    • Lift up the inverter cable with one hand, and carefully thread it around the heat sink. The inverter cable is still attached to the logic board, so be careful not to put too much strain on the cable.

    • Support the heat sink with both hands, and carefully lift it out of the computer. Be careful not to bend the copper heat pipe connecting the two sections of the heat sink.

    • If you need to mount the heat sink back into the laptop, we have a thermal paste guide that makes replacing the thermal compound easy.


To reassemble your device, follow these instructions in reverse order.

Thank you so much for this wonderful step by step guide! (Though no EMI Finger here neither). By cleaning the terrible mess there was on the microprocessor, and replacing the paste with Artcic Silver, my laptop is 20 C below what it used to be!
