I had a Satellite P75 delivered to me in Africa. Based on an
online review, I bought this thinking that I could fit an mSATA SSD module on it.
When I got the laptop and opened it up, to my surprise there was no mSATA connector!
I got the local electronics guys to put in an mSATA connector, and when I connected an mSATA module, the SSD was not detected.
halleync,
This might be what is missing.
