3 Routine care, SATA drive guidelines, and disassembly preparation This chapter provides general service information for the computer. Adherence to the procedures and precautions described in this chapter is essential for proper service. CAUTION: When the computer is plugged into an AC power source, voltage is always applied to the system board. The power cord must be disconnected from the power source before opening the computer to prevent system board or component damage.
Preventing electrostatic damage to equipment Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree of sensitivity. The following 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. ● Protect all electrostatic-sensitive parts and assemblies with conductive or approved containers or packaging.
● Keep work area free of non-conductive materials such as ordinary plastic assembly aids and Styrofoam. ● Use field service tools, such as cutters, screwdrivers, and vacuums, that are conductive.
● Never cover the ventilation slots on the monitor with any type of material. ● Install or enable power management functions of the operating system or other software, including sleep states. Routine care General cleaning safety precautions 1. Never use solvents or flammable solutions to clean the computer. 2. Never immerse any parts in water or cleaning solutions; apply any liquids to a clean cloth and then use the cloth on the component. 3.
● If you want to remove a key, use a specially designed key puller to prevent damage to the keys. This tool is available through many electronics supply outlets. CAUTION: Never remove a wide, level key (like the space bar) from the keyboard. If these keys are improperly removed or installed, the keyboard may not function properly. ● You can clean under a key with a swab moistened with isopropyl alcohol and then squeezed out. Be careful not to wipe away lubricants necessary for proper key functions.
Cables and connectors Most cables used throughout the unit are flat, flexible cables. These cables must be handled with care to avoid damage. Apply only the tension required to seat or unseat the cables during insertion or removal from the connector. Handle cables by the connector whenever possible. In all cases, avoid bending or twisting the cables, and ensure that the cables are routed in such a way that they cannot be caught or snagged by parts being removed or replaced.
