 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 loose. 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.

 Top Shield  Important:
   If you are installing the same top shield, remove the EMI finger by 
twisting it off of the shield. If you are replacing the top shield, make sure the shield 
does not have the EMI finger attached. A new foam pad on the trackpad overrides 
the need for the EMI finger.
