F 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.
G Routine Computer Care and Shipping Preparation Routine Computer Care Follow these suggestions to take care of the computer and monitor: Hardware Reference Guide ■ Operate the computer on a sturdy, level surface. Leave a 3-inch (7.6-cm) clearance at the back of the system unit and above the monitor to permit the required airflow. ■ Never operate the computer with the cover or side panel removed. ■ Never restrict the airflow into the computer by blocking the front vents or air intake.
Routine Computer Care and Shipping Preparation Optical Drive Precautions Be sure to observe the following guidelines while operating or cleaning the optical drive. Operation ■ Do not move the drive during operation. This may cause it to malfunction during reading. ■ Avoid exposing the drive to sudden changes in temperature, as condensation may form inside the unit. If the temperature suddenly changes while the drive is on, wait at least one hour before you turn off the power.
Routine Computer 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.
