 Bottom Case 14. If you are replacing any additional parts at this time, remove the two springs from the 
battery compartment so they do not fall out and get lost.

battery compartment are in place before installing the bottom case. Each spring has 
a plastic cap on one end. The cap should fit securely on the spring, and the curved 
side of the cap should be positioned against the inner frame. The springs have a 
small amount of grease on them; do not wipe away the grease.
