Product Description
1.4 Design Overview
This section presents a design overview of key parts and features
of the HP Notebook Expansion Base. Refer to Chapter 3,
“Illustrated Parts Catalog,” to identify replacement parts, and
Chapter 5, “Removal and Replacement Procedures,” for
disassembly steps.
The Expansion Base provides the following device connections:
■ Expansion cable
■ S/PDIF (Sony/Philips Digital Interface) audio connector
■ Audio out/Headphone jack
■ Composite out
■ RJ-11 (modem) connection (from wall to Expansion Base)
■ RJ-11 (modem) connection (from Expansion Base to
notebook)
■ RJ-45/Ethernet port
■ Six USB 2.0 connectors
■ S-Video out
■ Serial port
The HP Notebook Expansion Base uses electrical fans for
ventilation. The fans are controlled by a temperature sensor and
are designed to turn on automatically when high temperature
conditions exist. These conditions are affected by high external
temperatures, system power consumption, power
management/battery conservation configurations, and software
applications. Exhaust air is displaced through the ventilation grill
located on the right side, left side, and rear panel of the unit.
CAUTION: To properly ventilate the HP Notebook Expansion Base,
allow at least a 7.6-cm (3-inch) clearance on the left and right sides of
Ä
the unit.
