Introduction

The heat sink and fan together help to keep the processor cool and happy.

Release the tabs on each side of the RAM chip at the same time.  These tabs lock the chip in place and releasing them will cause the chip to "pop" up.

  • Pull the chip directly out from its connectors. If there is a second RAM chip installed, pop it out in the same manner.

  • This is a diagram of the trackpad ribbon clamp connector you will disconnect in the next step.

  • 1) With your fingernails, grasp the locking bar on either side slide it a small amount (about 1/16" or 2 mm) towards the battery.

  • 2) After disengaging the locking bar, slide the cable out of the connector.

Where can I get a replacement clip for the ribbon cable?

For this step, you only need to move the connector about 2 mm. Pulling too hard or too far will damage the connector.

  • Loosen the trackpad connector by pulling the locking bar toward the battery housing, using the tips of your fingers.

  • Slide the trackpad cable out of the loosened connector.

  • When reattaching the trackpad ribbon cable, make sure that the orange cable is slid into the connector above the locking bar.

  • Note: When reassembling the case, the trackpad cable can get stuck below the slot to the motherboard. It's possible to nudge it out slowly by gently prodding it on either side with a small screwdriver. You don't need to use much force to do this. Eventually it will just pop back out and you can reconnect as per the instructions above. Also, note that the locking bar comes loose so if you see a little piece of plastic lying around when reassembling, that's what it is. :)

    • Three 1.7 mm Phillips from the front edge of the battery compartment.

    • One 3.9 mm T8 Torx to the right of the memory card.

    • Three 12.4 mm fully threaded Phillips from the center of the row of screws along the back edge of the case.

    • Two 15.1 mm 2.5 mm threaded Phillips, one from either end of the row of screws along the back edge of the case.

i believe that you have the torx screws reversed here. The longer one should go on the left and vise versa.

BE VERY CAREFUL when replacing the keyboard to thread the keyboard ribbon cable through the slot. The steps didn't appear to make this warning and when I replaced all screws, found that it was jammed and would not come through to connect with the connector. I had to undo a lot of steps to go back and rethread it properly.

The optical drive ribbon cable is very fragile. Be sure to gently lift up the cable on the sides. Do not lift up on the cable from the end closest to the display.

  • If the logic board does not immediately come free, it may be necessary to soften the thermal paste between the logic board and heat sink. You can soften the thermal compound using a hairdryer. Move the hairdryer back and forth between the two fans about one inch above the logic board for one minute. At this point, logic board should now come free easily.

Grasp the logic board at the left edge with one hand and at the thinnest section with the other hand. Lift the left edge of the board up to approximately a 30 degree angle (if you don't have your protractor handy, just lift until the DVI port clears the right hinge).

Important. When you reinstall a logic board, you'll need to replace the thermal paste that goes between the processor on the logic board and the heat sink. Failure to remove the old paste and apply a new layer can cause the computer to overheat and sustain damage. The following steps refer to replacing the thermal paste between the processor and heat sink; follow these steps only when you are ready to place the logic board in the computer.

  • Use a firm plastic edge to scrape the thermal material off the raised copper heat conduit in three places. Clean the surface with rubbing alcohol.

From each complete hinge assembly, remove two Torx T6 screws from the outside of each set, leaving two remaining in the middle of each hinge. On each side, the two screws closer to the edge of the computer are shorter than the two screws closer to the center of the computer. Then remove the two inner screws from each hinge assembly.  There are 8 screws total.

when going backwards, be sure to check the previous step before performing this one, to line up the black plastic bits to their places - just inside of the metal screws. if you attach the display without lining them up, you will have to remove it again to re-align them.

When reassembling the display, check to see that the hinges are seated properly before reinstalling the 8 screws of the two hinges.  There is a metal phalange on the inside end of each hinge assembly that must be pointed downward and fit into a slot below the inside edge of the hinge.  If not, the inside end of each hinge will sit too high and the plastic retaining bracket for the wiring will not sit down properly.
