Step 7 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.

Step 8 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 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.

Step 9 Gently press the SODIMM down using your index fingers, distributing even pressure across the module until it locks into the tabs. (See Figure 56b.)

Caution Excessive pressure can damage a SODIMM socket.

Step 10 Verify that the release levers are flush against the side of the socket. If they are not, the SODIMM might not be seated properly.

Step 11 If the module appears misaligned, carefully remove it and reseat it, ensuring that the release lever is flush against the side of the SODIMM socket.

Step 12 If there is a retaining clip, insert it by sliding the clip between the metal strain relief and the plastic latch. (See Figure 57.)
