Figure55 SODIMM with Key in Face-up Position
Step7 The SODIMM must be lined up at a 45-degree angle. (See Figure 56a.)
Note When the key is in the face-up position, the metal traces on the left side of the key measure 0.9 inch
(23.20 mm). The metal traces on the right side of the key measure 1.29 inches (32.80 mm). The
SODIMM can not be inserted until the keys are lined up properly.
Step8 Place both thumbs at the end of the socket and use your index fingers to guide the module into the socket
until it is fully seated.
Be sure that your index fingers are located on the outer corners of the SODIMM to maintain even
pressure when the module is being seated in the socket.
