Using the CD or DVD Player (selected models) 
The multimedia buttons on the front of the notebook control the CD/DVD player, and work in much 
the same way as do the controls of a standalone CD or DVD player. The player operates whether the 
notebook is on, off, on standby, or in hibernation. (When the notebook is on, the volume control 
buttons also govern the volume for most audio applications.) 
If the notebook is off, on standby, or in hibernation, slide the multimedia power switch to the left to 
activate the player. For details about using the CD/DVD player, see the notebook’s Reference Guide.

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 electrical connections among the notebook’s replaceable electronic 
modules. In addition, the table on page 1-15 lists the roles that the replaceable modules play in each of 
the notebook’s functional subsystems.
