Internal Design
The motherboard PCA is the central component of the notebook’s design, and plays a role in virtually
all system functions. The CPU module and most other subsystems connect to the motherboard.
The following figure shows the connections among the notebook’s replaceable electronic modules. In
addition, the table on page 1-18 lists the roles that the replaceable modules play in each of the
notebook’s functional subsystems.

  Caution
 
Always provide proper grounding when performing repairs. Without proper
grounding, an electrostatic discharge can damage the notebook and its
components.
 
Notes
 
To reassemble a component, perform the removal procedure in reverse order. Any special notes
required for reassembly are included at the end of each section.
 
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 notebook. (The symbol at the left represents an M2.5×5mm T-head screw.)
