Thank you very much for this explanation!
I don't really understand what you mean with the bottom of the notebook - do
you man the piece of plastic which hides the mainboard?
I mean otherwise the photos of the mainboard actually show the bottom of the
notebook.
So I have to remove all screws on the mainboard and turn it around; I'm
afraid some connections are fixed with glue.
Will not be an easy task for me.
This metal strip has a special name? I can't type "special metal strip for
mounting a smaller wifi card where a bigger one was before" ;)
Perhaps I find a not-so-clean solution.
