How to check if laptop supports mSATA?

 I have Dell inspiron 7520SE  laptop which has two configurations with mSATA connection and preinstalled mSATA card and without mSATA connection. Mine is without preinstalled mSATA card, but I found in bios

mSATA Device : [Not detected]

So does that mean my laptop supports mSATA (but it is empty) or this is just some error, and is there a way to check if my laptop has support for mSATA withou pulling it apart ?
