Starting in Step 10 there are very delicate connectors that are easily broken. I first attempted to lift one with a spudger and noticed it begin to crack. I found an alternative way that worked perfectly for all of these types of connectors. Using 2 straight pins, press the point of each one just on either side of the connector, between the connector and the housing. Then use each pin to evenly pry the connector up. It will pop right out of the socket with no damage.
My macbook has been gradually getting hotter and running slower. Recently it started displaying some weird behavior that I assumed was a failing HD since it's 5 years old. I ran the extended Apple Hardware Test (more than once for confirmation) and got the following error: 4SNS/1/40000000: TN1D-104.000. Googling suggested that the CPU's northbridge was reaching a temperature of 104 deg. C and that macbooks have issues with overheating that can be attributed to poor application of thermal paste.
I followed this guide. The fan, heatsink fins and the underside of the logic board were almost completely clogged with dirt and cat hair. Got rid of it that, cleaned the excessive globs of dried up thermal paste, reapplied thermal paste and put everything back together. The macbook is now running cooler and faster and video is running quite smoothly which was an issue previously. I reran the Apple Hardware Test which reported, "No trouble found".

Hi, I have a mac book 4.1 with a gma x3100 32bit graphic chip, white plastic enclosure just like the one in the pictures.
The tutorial seems pretty detailed, great job, I feel confident I can get through without problems but I have a couple of questions.
Which logic board model will suit my mac book best, I also read that the heat sink and the SuperDrive connectors may be different, is that true?
thanks!
Andrea.

This page is for a macbook 6.1 or 7.1. Wrong page for your mac!

According to this page http://support.apple.com/kb/HT1651?viewl..., the 8 screws are not identical.
Can anybody tell me where each kind of screw is supposed to go?

They are all 100% Identical. You were probably looking at a different model, or Apple has entered the wrong information... Hey, It happens...

The screws on the Late 2009 are identical. The blue lock compound might make tightening some require a little more effort.

hi, i just got back from the apple store and they are really keen for me to upgrade to a new laptop since my battery is old and the screen is cracked, so glad i found ifixit i would love to upgrade this puppy! gonna make it a real sleeper! styler hall wrote about sticking 16 gb of ram in his a 1342 ? is this a simply mather of ordering 3 4gb sticks ?aslo i currently have 4 gb and would like to upgrade to 8 ( or indeed 16) does that mean i need to buy all new sticks or can i continue to use the old one and stick a new one next to it ?
thanks again mick van aar, perth western aus.

The A1342 will take up to 16 GB of RAM, however, there are only two RAM slots, so use two 8-GB RAM modules. Other World Computing (OWC) is a great reference source for info on exactly which RAM to use with which model; prices are usually much better on EBay though. Add an SSD from OWC and your machine will really scream!
I hope that helps!

Gregoire is right. The 8 screws are absolutely NOT identical, I’m looking at them right now, weeowey weeowey.

I just wanted to say that, in 2020, i used these instructions to replace the magsafe socket on my A1286, mid-2012, pre-Retina MacBook Pro. The internal layout is not quite the same but close enough for me to do the job. I skipped the steps of fully disconnecting the fans and speakers because of what others had said about breaking the sockets. it just meant I had to be extremely careful when lifting up the main board so that I did not tear and break the connections. I was able to disconnect the old magsafe socket with the board flat and in situ, but there was no where near enough room to be able to aline and press home the new par home. Reluctantly i had to lever up the board. This was difficult as there is a tapped post that holds a screw in the way close to where the USB sockets are, that prevented the board lifting up and out. I had to be quite forceful to manouevre the sockets out from the edge of the case.
