A 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.
●
Place parts on a grounded surface before removing them from their containers.
●
Avoid touching pins, leads, or circuitry.
●
Always be properly grounded when touching a static-sensitive component or assembly.
●
Grounding Methods
There are several methods for grounding. Use one or more of the following methods when handling or
installing electrostatic-sensitive parts:
Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist
●
straps are flexible straps with a minimum of 1 megohm +/- 10 percent resistance in the ground
cords. To provide proper ground, wear the strap snug against the skin.
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.
NOTE: For more information on static electricity, contact an HP authorized dealer, reseller, or service
provider.

B 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:
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 above the monitor to permit the required airflow.
Never restrict the airflow into the computer by blocking any vents or air intakes. Do not place the
●
keyboard, with the keyboard feet down, directly against the front of the desktop unit as this also
restricts airflow.
Never operate the computer with the access panel or any of the expansion card slot covers
●
removed.
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.
●
Install or enable power management functions of the operating system or other software, including
●
sleep states.
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.
36 Appendix B Computer Operating Guidelines, Routine Care and Shipping Preparation ENWW
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. If you operate the unit immediately, it may malfunction while reading.
Avoid placing the drive in a location that is subject to high humidity, extreme temperatures,
●
mechanical vibration, or direct sunlight.
Cleaning
Clean the panel and controls with a soft, dry cloth or a soft cloth lightly moistened with a mild
●
detergent solution. Never spray cleaning fluids directly on the unit.
Avoid using any type of solvent, such as alcohol or benzene, which may damage the finish.
●
Safety
If any object or liquid falls into the drive, immediately unplug the computer and have it checked by an
authorized HP service provider.
Shipping Preparation
Follow these suggestions when preparing to ship the computer:
1. Back up the hard drive files on PD discs, tape cartridges, or CDs. Be sure that the backup media
is not exposed to electrical or magnetic impulses while stored or in transit.
NOTE: The hard drive locks automatically when the system power is turned off.
2. Remove and store all removable media.
3. Turn off the computer and external devices.
4. Disconnect the power cord from the electrical outlet, then from the computer.
5. Disconnect the system components and external devices from their power sources, then from the
computer.
NOTE: Ensure that all boards are seated properly and secured in the board slots before shipping
the computer.
6. Pack the system components and external devices in their original packing boxes or similar
packaging with sufficient packing material to protect them.
