Internal Design

The motherboard PCA is the central component of the notebook’s design. It 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. Table 1-9on page 1-28lists the roles that these modules play in the notebook’s functional subsystems.
