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

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.

ÄCAUTION: 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 the unit.
