the case. If the module latch assembly does come loose from the case:
a. Carefully reinsert the spring onto the slider on the module latch, and 
reinstall the module latch into the holding features on the inside of the 
case.
b. Ensure that the slider is inserted in its respective hole, that the side of 
the latch with the two bumps is facing the back of the case, and that 
the surface with the wear ribs is facing the bottom of the case (see 
Figure 21).
7. Snap in the new latch button from the bottom of the base, making certain 
its snap tabs are fully engaged in the module latch.
8. Ensure that the newly installed latch moves smoothly and freely when 
pushed and released.
