3 Computer Operating Guidelines, Routine Care and Shipping Preparation Computer Operating Guidelines and Routine Care Follow these guidelines to properly set up and care for the computer and monitor: Hardware Reference Guide ■ Keep the computer away from excessive moisture, direct sunlight, and extremes of heat and cold. ■ Operate the computer on a sturdy, level surface. Leave a 10.2-cm (4-inch) clearance on all vented sides of the computer and monitor to permit the required airflow.
Computer Operating Guidelines, Routine Care and Shipping Preparation ■ Turn off the computer before you do either of the following: ❏ Wipe the exterior of the computer with a soft, damp cloth as needed. Using cleaning products may discolor or damage the finish. ❏ Occasionally clean the air vents on all vented sides of the computer. Lint, dust, and other foreign matter can block the vents and limit the airflow.
Computer Operating Guidelines, Routine Care and Shipping Preparation Shipping Preparation Follow these suggestions when preparing to ship the computer: 1. Back up the hard drive files on PD discs, tape cartridges, CDs, or diskettes. Be sure that the backup media is not exposed to electrical or magnetic impulses while stored or in transit. hard drive locks automatically when the system power is ✎ The turned off. 2. Remove and store any program diskettes from the diskette drives. 3.
4 Electrostatic Discharge A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device. Preventing Electrostatic Damage To prevent electrostatic damage, observe the following precautions: ■ Avoid hand contact by transporting and storing products in static-safe containers. ■ Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
Electrostatic Discharge ■ Use heelstraps, toestraps, or bootstraps at standing workstations. Wear the straps on both feet when standing on conductive floors or dissipating floor mats. ■ Use conductive field service tools. ■ Use a portable field service kit with a folding static-dissipating work mat. If you do not have any of the suggested equipment for proper grounding, contact an HP authorized dealer, reseller, or service provider.
