Hi Adam,
First of all thanks so much for your post! I am really sorry, but despite my nick name I am not a native French speaker. This is why I write in English. (Not my native tongue either, but at least I am fluent as I have been living in the UK for the past 12 years).
However, I tried to understand what you are saying by using my really very basic school French.
Just for communication's sake I will repeat what I think I understood.
You said something about Apple Store technicians changing parts like the motherboard when they do not know much about its components:
"They do not know ho to use a multimeter/circuit analyser or an oscilloscope for detecting a fault or trace a signal and they do not know the difference between an active or passive component. So how do you expect them to be able to repair your computer or your motherboard?"
"1) You must open up your mac book."
(I guess, you mean really unscrew and open it?)
"2) Connect your battery charger, check if it starts"
(I guess, 'it' is 'the computer')
"3) If your battery charged up and it it still does not start"
(my battery has been faulty for the past two years. When I plugged in my magsafe adaptor the macbook pro would start up and run off the mains just fine - before the motherboard replacement, that is)
"4) Vérifie les nappes de l'inter marche arrêt, tu n'a qu'à suivre ) partir de ton bouton Power
Check the ... les nappes de l'inter marche arrêt" (sorry you lost me here... I cannot translate it)
"6)Check the solders."
"After having checked all this and you did not find anything, then you must have a power supply problem on your motherboard. With this I will not able to help you much unless you know the active and passive components because this kind of problem you tackle at the CSM (?)and the BGA (ball grid array) components. If you (metrises?) them you will be able to detect the fault easily."
''"Be careful not to hand your computer over to just anybody, it will usually only make things worse. Most of the computer
repair people possess no competence in the field of information technology."''
I think you might be right and Apple technicians really are not highly trained specialist. And indeed they do not seem to know much about the inner workings of a, say, motherboard. Except perhaps about replacing it.
The reason why I used the Mac Store to replace my mother board was, it was a free replacement because of a faulty Nvidea GPU failure (widely publicised on the internet).
Let me know, whether I understood you okay-ish and then I can see what I can do for myself. But I am not a great techy (no knowledge of active and passive components) so in the end I will probably have to rely on someone tech minded.
Thanks also for your e-mail address. Much appreciated.
Mine is youssou[at]linuxmail.org if you prefer to continue this conversation by e-mail. But then of course people with a similar problem will not be able to find the post.
All the best,

Why not take it back to them again and tell them it will not boot? Sounds like they need to fix the issue.
