Remove the latch button by using a plastic scribe to push on the snap
tabs until the latch button is released from the bottom case.
To prevent the latch assembly from coming loose, apply pressure to the latch and spring while removing the latch button. If the latch assembly does come loose from the case:
Slide the spring onto the slider on the latch, and reinstall the latch
into the holding features on the inside of the bottom case.
Ensure that the slider is inserted into the hole, that the side of the
latch with the two bumps is facing the back of the case, and that
the side with the wear rib is facing the front of the case.
NOTE: The latch will not function properly if the slider is oriented
incorrectly.
