Hi Kevroll,
Okay, the best source of information is the Hardware Maintenance Manual kindly provided by Lenovo. Here's where you can download a copy.

Page 46 shows how to remove the SSD (I assume that's what you meant rather than "SAD").

Note that it does say "on select models", so it's entirely possible yours doesn't have a spot for an SSD, but if it does, that's where it will be.
