D 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.
E 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.
