The expansion port allows you to connect the computer to
an expansion device such as the optional Slim Port
Replicator. A shutter door protects this port.
The spring-loaded main battery release latch locks and
unlocks the battery module, which holds the main battery in
place.
The removable main battery module powers the computer
when you’re away from an AC power source. Using the main
battery, you can work for several hours in full power mode
without an external power source.
For more information about inserting or removing the main
battery, see “Changing the main battery” on page 88.
The speaker allows you to hear sounds, such as system
alarms or audio files played on optional media devices.
The expansion memory slot cover protects the slot that
holds any extra memory added to your computer. For more
information on expanding your computer’s memory, see
“Installing additional memory (optional)” on page 40.
