The next few steps bring your hands close to the exposed face of the power supply. Do not touch the face of the power supply or any of the exposed solder. Touching it risks a high voltage shock from the many large capacitors attached to the board.
Use the tip of a spudger to push each side of the power button cable connector and gently walk it out of its socket.
When working on the power supply, be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply. Only handle the board by the edges.
When installing the logic board, take care to align the exterior I/O ports correctly. The logic board can sit crooked even when secured with all its screws.
Use a USB flash drive and/or ethernet cable to ensure the logic board is seated correctly while you screw it in.
Holy jesus - just to replace/upgrade some RAM? Wow. What advice do you have for the final stage of reassembly if you've had to take the strips of adhesive off - what (if anything) do you replace it with?
James, in the parts section at the top you can purchase the adhesive strips that are a custom fit ([关联产品丢失或禁用: IF173-005]). I just replaced the hard drive and these strips are quite easy to work with. It's just a pain that you have to replace the adhesive anytime you need to go inside. Apple is getting lazy.
This was very easy to follow. The number of steps seem high, but half are just removing the display to make sure you are very careful with the fragile glass, so there are really only about 35 steps. You may also need to remove the right speaker before disconnecting the 4 AirPort/Bluetooth antennae, currently before step 50. The speaker is shown in earlier pics, then "disappears."
yes from what I went through it made sense to unscrew both speakers so you can move them a little bit to get things down like that and plugging the hard drive back in
