Keyboard The heat sink in your computer may be slightly different from the one shown in Figure 4-25. There may be a conductive sponge added to your computer. Top Assembly If you have a Latitude MMX computer, use the following figure for the removal and replacement procedure. The top assembly has two hard-disk drive contact springs on the underside of the top assembly. There is also a conductive sponge added to the top assembly (see the following figure).
