1-12 Product Information HP OmniBook 7100

Internal Design

The motherboard PCA is the central component of the OmniBook design. It plays a role in virtually

all system functions. The CPU module (MMO) and most other subsystems connect to the

motherboard.

The following figure shows the connections among the replaceable electrical modules. As a substitute

for a functional block diagram, see the table on page 1-13—it lists the roles the replaceable modules

play in each of the functional subsystems.
