5 Routine Care 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. You must disconnect the power cord from the power source before opening the computer to prevent system board or component damage.
Electrostatic Discharge Information A sudden discharge of static electricity from your finger or other conductor can destroy static-sensitive devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic device exposed to electrostatic discharge (ESD) may not appear to be affected at all and can work perfectly throughout a normal cycle. The device may function normally for a while, but it has been degraded in the internal layers, reducing its life expectancy.
● Always be properly grounded when touching a sensitive component or assembly. ● Avoid contact with pins, leads, or circuitry. ● Place reusable electrostatic-sensitive parts from assemblies in protective packaging or conductive foam. Personal Grounding Methods and Equipment Use the following equipment to prevent static electricity damage to equipment: ● Wrist straps are flexible straps with a maximum of one-megohm ± 10% resistance in the ground cords.
● Conductive bins and other assembly or soldering aids ● Conductive foam ● Conductive tabletop workstations with ground cord of one-megohm +/- 10% resistance ● Static-dissipative table or floor mats with hard tie to ground ● Field service kits ● Static awareness labels ● Wrist straps and footwear straps providing one-megohm +/- 10% resistance ● Material handling packages ● Conductive plastic bags ● Conductive plastic tubes ● Conductive tote boxes ● Opaque shielding bags ● Transparen
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. Always unplug the computer when cleaning with liquids or damp cloths. 4. Always unplug the computer before cleaning the keyboard, mouse, or air vents. 5. Disconnect the keyboard before cleaning it. 6.
● 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. CAUTION: Never remove a wide leveled key (like the space bar) from the keyboard. If these keys are improperly removed or installed, the keyboard may not function properly. ● Cleaning under a key may be done with a swab moistened with isopropyl alcohol and 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.
