1.  Place the SLIM into the socket almost vertically (about 75-
degree angle), making sure that it is properly oriented and 
fully inserted into the socket. 
2.  Press downward and sideways on the SLIM until it latches 
into the socket. Do NOT force the SLIM, the installation 
process requires a small force and should be very smooth and 
easy. If you encounter resistance then re-check the orientation 
and insertion depth.
