board and the LCD panel.

Bottom Case Assembly Removal

The parts of your computer may be different from the parts shown in Fig-

ure 4-22, “Bottom Case Assembly Removal,” of the Service Manual (Figure 22

of the Parts Removal and Replacement Guide). The superpart docking EMI clip

and superpart serial EMI clip may be smaller. The superpart assembly may also

look different. The upper I/O bracket clip has been renamed the deck buoy.
