No sound from the headphone jack? Swap out the sound card!

Edit Step 1 Battery  ¶

Edit Step 1 Battery  ¶ 

  • Orient the computer so that the side with the line of screws on it is away from you.

  • Use your thumbs to push both battery release tabs away so that the edge of the battery lifts up.

  • Lift the battery out of the computer.

Edit Step 2 Upper Case  ¶

Edit Step 2 Upper Case  ¶ 

  • Remove the three identical Phillips screws from the memory door.

Edit Step 3  ¶

Edit Step 3  ¶ 

  • Lift the memory door up enough so that you can get a grip on it, and slide it toward you, pulling it away from the casing.

Edit Step 4  ¶

Edit Step 4  ¶ 

  • 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.

Edit Step 5  ¶

Edit Step 5  ¶ 

  • 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.

Edit Step 6  ¶

Edit Step 6  ¶ 

  • 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. :)

Edit Step 7  ¶

Edit Step 7  ¶ 

  • Remove the following 10 screws from the bottom case:

    • 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.

    • One 6.9 mm T8 Torx at the left edge of the memory compartment.

    • 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.

Which screw driver I have to use here?

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

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

oops, my bad. You're right.

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.

Take Care while reassembling,

that the Trackpad-Cable does not binds under the motherboard,

otherwise you cant connect it again on the other side.

on mine, the speaker wire was run under the IDE ribbon cable, so no rerouting was needed
