Internal Design

The motherboard PCA is the central component of the computer’s design, and plays a role in virtually all system functions. Most components connect directly to the motherboard.

The following figure shows the connections among the replaceable components in the computer and expansion base. In addition, Table 1-9 on page 1-20 lists the roles that these components play in the functional subsystems of the computer and expansion base.

Caution

Always provide proper grounding when performing repairs. Without proper grounding, an electrostatic discharge can damage the computer or expansion base and their components.

Notes

Reassembly steps are the reverse of the removal/disassembly steps. Reassembly notes are included at the end of each removal procedure.

Symbols like this throughout this chapter show approximate full-size screw outlines. You can use these to verify the sizes of screws before you install them. Installing a wrong-size screw can damage the unit. (The symbol at the left represents an M2.5×5mm T-head screw.)
