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  
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 cover or side panel 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.

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.  
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.

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.

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.
