Maintenance and Service Guide 1­21 Product Description 1.5 Design Overview This section presents a design overview of key parts and features of the notebook. Refer to Chapter 4, "Illustrated Parts Catalog," to identify replacement parts, and Chapter 6, "Removal and Replacement Procedures," for disassembly steps. The system board provides the following device connections: AMD Turion 64 MT, Turion 64 ML, and Mobile AMD Sempron processors Audio Display Hard drive Keyboard and TouchPad Memory module Mini PCI communications devices PC Card Ä CAUTION: To properly ventilate the notebook, allow at least a 7.6-cm (3-inch) clearance on the left and right sides of the notebook. The notebook uses an electric fan for ventilation. The fan is controlled by a temperature sensor and is designed to be turned on automatically when high temperature conditions exist. These conditions are affected by high external temperatures, system power consumption, power management/battery conservation configurations, battery fast charging, and software applications. Exhaust air is displaced through the ventilation grill located on the left side of the notebook. 1­22 Maintenance and Service Guide 2 Troubleshooting Å WARNING: Only authorized technicians trained by HP should repair this equipment. All troubleshooting and repair procedures are detailed to allow only subassembly-/module-level repair. Because of the complexity of the individual boards and subassemblies, do not attempt to make repairs at the component level or modifications to any printed wiring board. Improper repairs can create a safety hazard. Any indication of component replacement or printed wiring board modification may void any warranty or exchange allowances. 2.1 Computer Setup Computer Setup is a preinstalled, ROM-based utility that can be used even when the operating system is not working or will not load.
