  11. There's a trackpad and keyboard ribbon connecting the upper case to the logic board, so don't pull the upper case off entirely just yet.

    • There's a trackpad and keyboard ribbon connecting the upper case to the logic board, so don't pull the upper case off entirely just yet.

    • Starting near the display and working around to the front of the computer, pry up on the upper case. A plastic opening tool or a medium hard guitar pick may help you to do this.

    • The upper case is likely to stick at the connection above the optical drive. If this is the case, first free all other sides, then proceed to pull upward on the upper case from either side of the optical drive opening.

    • If you stand the base on end to get a better look you may displace the total of 4 grey plastic clips that hold the keyboard in place. Don't panic. They slide into slots at the top right-most edge near the CD drive.

  12. While holding up the upper case, pull up the black tab of the silver cable away from its connector. If there is no black tab, you can also use a spudger to gently pry the connector from its housing. This connector is tall, so be sure to pry straight up. If you happen to break your upper case cable when removing the upper case, we stock the cable individually and we have a guide that makes replacing it easy.

    • While you have the upper case removed, you may want to take the opportunity to remove dust, hair, etc. It's best to use a can of compressed air, though if you use a brush, make sure that its bristles are made of a material (usually animal hair) that doesn't generate static electricity, which can destroy electronics.

    • Upon reassembly, there are 4 grey plastic clips on the optical drive side of the keyboard (refer to second picture). They must be installed in their slots for the keyboard to snap in properly.

    • To make the reassamble process easier, it's better to pull out the clips first by pulling it straight up gently. Be careful not to put too much strength because it will break.

Thanks so much for this guide! My mac wouldn't turn on after spilling some wine on it a few days before. After I followed these steps and let the parts lay out to dry overnight (after cleaning everything with rubbing alcohol), I put it back together and it turned on!! Thank you a million times!

Double-sides sticky tape is very useful (to keep the screws together) on top of numbered post-it notes for the steps.

The shop wanted over $700 ($600 for parts, $90+ for labor) to fix it, which I definitely wasn't going to pay, so I decided to fix it myself. I spent right at $150 for a new logic board, magsafe board, and RAM upgrades and delved into the depths of the Macbook. I followed every step of the guide closely and she started right up after reassembly. Great guide, thanks!

Great Guide - i used zip-lock bags for screws and wrote the step numbers on each.

I've managed to replace a macbook 1,1 logic board with a macbook 2,1 (2GHz) one, and replaced a 4,1 on another machine (which looks interchangeable with older ones)

It is NOT possible to replace these older boards with a newer macbook 5.2 board because ALL the connectors are different, and the screw-holes are in different places.

Managed to revive my years old dead Macbook! Glad I found this guide and helped me diagnose and fix the problem. (Only wish I would have found this BEFORE I started disassembling my Macbook. Half the beginning screws don't have a home now. Whoops) Overall great guide. The alternate pictures were great since they were more in-line with mine. Easy to follow, and everything turned out great. Thanks!
