To access FRUs in the display assembly, remove the display assembly as
described in the following procedure:

6. Using two pairs of pliers, lift upwards on the left and right side of the
display cable interface board and remove the board from the unit
while pulling the ground cable from the base assembly.

Phillips-head screws that secure the display hinges to the Base Case
Assembly.
8. Ensure that the display cables are free from the Top Case Assembly
and remove the Display Assembly.
