Safety warning notice
WARNING! To reduce the possibility of heat-related injuries or of overheating the device, do not place
the device directly on your lap or obstruct the device air vents. Use the device only on a hard, at surface. Do
not allow another hard surface, such as an adjoining optional printer, or a soft surface, such as pillows or rugs
or clothing, to block airow. Also, do not allow the AC adapter to contact the skin or a soft surface, such as
pillows or rugs or clothing, during operation. The device and the AC adapter comply with the user-accessible
surface temperature limits dened by the International Standard for Safety of Information Technology
Equipment (IEC 60950-1).

3 Routine care, SATA drive guidelines, and
disassembly preparation
This chapter provides general service information for the computer. Adherence to the procedures and
precautions described in this chapter is essential for proper service.
CAUTION: When the computer is plugged into an AC power source, voltage is always applied to the system
board. You must disconnect the power cord from the power source before opening the computer to prevent
system board or component damage.
Electrostatic discharge information
A sudden discharge of static electricity from your nger or other conductor can destroy static-sensitive
devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic device
exposed to electrostatic discharge (ESD) may not appear to be aected at all and can work perfectly
throughout a normal cycle. The device may function normally for a while, but it has been degraded in the
internal layers, reducing its life expectancy.
Networks built into many integrated circuits provide some protection, but in many cases, the discharge
contains enough power to alter device parameters or melt silicon junctions.
Generating static
The following table shows the following about static electricity:
●Dierent activities generate dierent amounts of static electricity.
●Static electricity increases as humidity decreases.

Preventing electrostatic damage to equipment
Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree of
sensitivity. The following packaging and grounding precautions are necessary to prevent damage to electric
components and accessories.
●To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes.
●Protect all electrostatic parts and assemblies with conductive or approved containers or packaging.
●Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.
●Place a container on a grounded surface before removing items from it.
●Always be properly grounded when touching a sensitive component or assembly.
●Avoid contact with pins, leads, or circuitry.
●Place reusable electrostatic-sensitive parts from assemblies in protective packaging or conductive
foam.
Personal grounding methods and equipment
Use the following equipment to prevent static electricity damage to equipment:
●Wrist straps are exible straps with a maximum of one-megohm ± 10% resistance in the ground cords.
To provide proper ground, a strap must be worn snug against bare skin. The ground cord must be
connected and t snugly into the banana plug connector on the grounding mat or workstation.
●Heel straps/Toe straps/Boot straps can be used at standing workstations and are compatible with
most types of shoes or boots. On conductive oors or dissipative oor mats, use them on both feet with
a maximum of one-megohm ± 10% resistance between the operator and ground.

Grounding the work area
To prevent static damage at the work area, use the following precautions:
●Cover the work surface with approved static-dissipative material. Provide a wrist strap connected to the
work surface and properly grounded tools and equipment.
●Use static-dissipative mats, foot straps, or air ionizers to give added protection.
●Handle electrostatic-sensitive components, parts, and assemblies by the case or PCB laminate. Handle
them only at static-free work areas.
●Turn o power and input signals before inserting and removing connectors or test equipment.
●Use xtures made of static-safe materials when xtures must directly contact dissipative surfaces.
●Keep work area free of nonconductive materials such as ordinary plastic assembly aids and Styrofoam.
●Use eld service tools, such as cutters, screwdrivers, and vacuums, that are conductive.
Electrostatic discharge information 9

Recommended materials and equipment
Materials and equipment that are recommended for use in preventing static electricity include the following:
●Antistatic tape
●Antistatic smocks, aprons, or sleeve protectors
●Conductive bins and other assembly or soldering aids
●Conductive foam
●Conductive tabletop workstations with ground cord of one-megohm ± 10% resistance
●Static-dissipative table or oor mats with hard tie to ground
●Field service kits
●Static awareness labels
●Wrist straps and footwear straps providing one-megohm +/- 10% resistance
●Material-handling packages
●Conductive plastic bags
●Conductive plastic tubes
●Conductive tote boxes
●Opaque shielding bags
●Transparent metallized shielding bags
●Transparent shielding tubes
Operating guidelines
To prevent overheating and to help prolong the life of the computer:
●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 in) clearance on all vented sides of
the computer and above the monitor to permit the required airow.
●Never restrict the airow 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 airow.
●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 airow. Be sure to unplug the computer before cleaning the air vents.
●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.
10 Chapter 3 Routine care, SATA drive guidelines, and disassembly preparation

●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.
Routine care
General cleaning safety precautions
1. Never use solvents or ammable solutions to clean the computer.
2. Never immerse any parts in water or cleaning solutions; apply any liquids to a clean cloth and then use
the cloth on the component.
3. Always unplug the computer when cleaning with liquids or damp cloths.
4. Always unplug the computer before cleaning the keyboard, mouse, or air vents.
5. Disconnect the keyboard before cleaning it.
6. Wear safety glasses equipped with side shields when cleaning the keyboard.
Cleaning the computer case
Follow all safety precautions in General cleaning safety precautions on page 11 before cleaning the computer.
To clean the computer case, follow the procedures described below:
●To remove stains or dirt, use one of the following:
–Alcohol-free glass-cleaning uid
–Solution of water and mild soap
–Dry microber cleaning cloth or a chamois (static-free cloth without oil)
–Static-free cloth wipes
●For stronger stains, use a mild dishwashing liquid diluted with water. Rinse well by wiping the surface
with a cloth or swab dampened with clear water.
CAUTION: Avoid strong cleaning solvents or germicidal wipes that can permanently damage your
computer. If you are not sure that a cleaning product is safe for your computer, check the product
contents to make sure that ingredients such as alcohol, acetone, ammonium chloride, methylene
chloride, and hydrocarbons are not included in the product.
●For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed because the alcohol will
evaporate quickly and not leave a residue.
●After cleaning, always wipe the unit with a clean, lint-free cloth.
●Periodically clean air vents on bezel and power supply. Also clean the internal chassis fans, heat sink
fans, and GPU fans (if present). For information about accessing internal components, see Removal and
replacement procedures on page 16. Dirty vents and fans can contribute to overheating, which leads
to shortened product life.
CAUTION: To reduce the risk of damage to computer components due to static discharge, do not use a
vacuum to remove debris.
