 Top Shield
Replacement Note:
 With the top shield removed, check the hard drive stiffener. 
Make sure it has a thin, foam strip backing. The stiffener can become lo\
ose. Make 
sure it is positioned over the hard drive and frame before replacing the\
 top shield.
If the foam backing is missing, order a trackpad kit (Apple part number\
 076-1078), 
and replace the stiffener with one from the kit.
