3 Removal and Replacement Preliminaries and Routine Care This chapter provides general service information for the computer. Adherence to the procedures and precautions described in this chapter is essential for proper service. Ä 3.1 CAUTION: When the computer is plugged into an AC power source there is always voltage applied to the system board. You must disconnect the power cord from the power source before opening the computer to prevent system board or component damage.
Removal and Replacement Preliminaries and Routine Care 3.1.2 Preventing Electrostatic Damage to Equipment Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree of sensitivity. The following proper packaging and grounding precautions are necessary to prevent damage to electric components and accessories. ■ To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes.
Removal and Replacement Preliminaries and Routine Care 3.1.4 Grounding Workstations To prevent static damage at the workstation, use the following precautions: ■ Cover the workstation with approved static-dissipative material. Provide a wrist strap connected to the work surface and properly grounded tools and equipment. ■ Use static-dissipative mats, foot straps, or air ionizers to give added protection. ■ Handle electrostatic sensitive components, parts, and assemblies by the case or PCB laminate.
Removal and Replacement Preliminaries and Routine Care 3.2 Routine Care 3.2.1 3.2.1 General Cleaning Safety Precautions ■ Never use solvents or flammable solutions to clean the computer. ■ Never immerse any parts in water or cleaning solutions, apply any liquids to a clean cloth and then use the cloth on the component. ■ Always turn off the computer when cleaning with liquids or damp cloths. ■ Always turn off the computer before cleaning the keyboard, mouse, or air vents.
Removal and Replacement Preliminaries and Routine Care Ä ■ Visible debris underneath or between the keys may be removed by vacuuming or shaking. ■ Canned, pressurized air may be used to clean debris from under the keys. Caution should be used as too much air pressure can dislodge lubricants applied under the wide keys. ■ If you remove a key, use a specially designed key puller to prevent damage to the keys. This tool is available through many electronic supply outlets.
Removal and Replacement Preliminaries and Routine Care 3.3.2 Screws The screws used in the computer are not interchangeable. They may have standard or metric threads and may be of different lengths. If an incorrect screw is used during the reassembly process, it can damage the unit. Compaq strongly recommends that all screws removed during disassembly be kept with the part that was removed, then returned to their proper locations. 3.3.
4 Removal and Replacement Procedures After completing all necessary removal and replacement procedures, run the Diagnostics utility to verify that all components operate properly. Ä 4.1 CAUTION: When the computer is plugged into an AC power source, there is always voltage applied to the system board. You must disconnect the power cord from the power source before opening the computer to prevent system board or component damage.
