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.
