This helps with getting the right angle. I used my fingers and the spudger to guide them back in. It took me easily 10-15 minutes to do this.
There is one thing though I find missing which concerns: 1)The rubber heat sink cover 2 The AirPort/Camera cables 3)The IO board cable All these are “glued” to the fan and you need to peel them off gently using the spudger, now while I noticed that some glue remains on each cable so they will kinda stick again, I wonder what kind of glue is this and where one can buy it? These individual instructions are re-used across multiple tutorials. If you are replacing the battery, you probably won’t need to remove the three connections from the Airport card; if you are replacing the display, you definitely need to replace them, because they are connected to the display. I just replaced the battery and the display in a single activity, so I pretty much had to remove everything.
Wrap one end of the wire a few times around one bolt, then tie it off with a knot. Do the same with the other bolt, leaving about 10” of wire between the two.
You can even check it has the same specs written on the cable. To be perfectly clear, we are talking about just the extension electrical cord from the outlet to the magsafe brick, and not the magsafe adapter itself. More (Read full answer) • Answered by Bozidar J from Kranj • on Jan 6, 2015.
