Recently I've opened up my Lifebook E754 as it became a bit clogged with dust inside. I noticed that there seems to be a slot that looks very similar to a M.2 slot next to the PCI-e slot. I've contacted my local shop where the notebook comes from and told me that it's meant for a WWAN module and they are not aware of any other possibilities for this slot (as no-one over there has tried so).
So I'm wondering whether a M.2 SSD would work in this slot? I guess that it may be recognized but not be able to boot from, that would be no problem actually.
Would anybody know this perhaps whether a M.2 SSD would fit and work in this slot?
