Small Form Factor All-in One 24 Chapter 4 Identifying the Chassis, Routine Care, and Disassembly Preparation
Electrostatic Discharge Information A sudden discharge of static electricity from your finger or other conductor can destroy staticsensitive 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.
● Keep electrostatic sensitive parts in their containers until they arrive at static-free stations. ● Place items on a grounded surface before removing them from their container. ● 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.
Recommended Materials and Equipment Materials and equipment that are recommended for use in preventing static electricity include: ● Antistatic tape ● Antistatic smocks, aprons, or sleeve protectors ● 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 footwea
● Do not stack computers on top of each other or place computers so near each other that they are subject to each other’s re-circulated or preheated air. ● If the computer is to be operated within a separate enclosure, intake and exhaust ventilation must be provided on the enclosure, and the same operating guidelines listed above will still apply. ● Keep liquids away from the computer and keyboard. ● Never cover the ventilation slots on the monitor with any type of material.
Cleaning the Keyboard Follow all safety precautions in General Cleaning Safety Precautions on page 28 before cleaning the keyboard. To clean the tops of the keys or the keyboard body, follow the procedures described in Cleaning the Computer Case on page 28. When cleaning debris from under the keys, review all rules in General Cleaning Safety Precautions on page 28 before following these procedures: CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from under the keys.
Power Supply Fan The power supply fan is a variable-speed fan based on the temperature in the power supply. CAUTION: The cooling fan is always on when the computer is in the “On” mode. The cooling fan is off when the computer is in “Standby,” “Suspend,” or “Off” modes. You must disconnect the power cord from the power source before opening the computer to prevent system board or component damage.
Hard Drives Handle hard drives as delicate, precision components, avoiding all physical shock and vibration. This applies to failed drives as well as replacement spares. ● If a drive must be mailed, place the drive in a bubble-pack mailer or other suitable protective packaging and label the package “Fragile: Handle With Care.” ● Do not remove hard drives from the shipping package for storage. Keep hard drives in their protective packaging until they are actually mounted in the CPU.
