The system board provides the following device connections: I I I I I I I I I Memory expansion board Hard drive Display Keyboard/TouchPad or pointing stick Audio Intel Pentium III processors Fan PC Card Modem or modem/NIC The computer uses an electrical fan for ventilation. The fan is controlled by a temperature sensor and is 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, battery fast charging, and software applications. Exhaust air is displaced through the ventilation grill located on the left side of the computer. Ä CAUTION: To properly ventilate the computer, allow at least a 3-inch (7.6 cm) clearance on the left and right sides of the computer. 1­16 Maintenance and Service Guide 2 Troubleshooting Å WARNING: Only authorized technicians trained by Compaq 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, no one should attempt to make repairs at the component level or to make 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 and Diagnostics Utilities Selecting Computer Setup or Compaq Diagnostics The computer features two Compaq system management utilities: I Computer Setup--A system information and customization utility that can be used even when your operating system is not working or will not load.
