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. The power cord must be disconnected 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 how humidity aects the electrostatic voltage levels generated by dierent
activities. A product can be degraded by 700 volts.
●Dierent activities generate dierent amounts of static electricity.
●Static electricity increases as humidity decreases.

Electrostatic discharge information 9

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-sensitive 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 items on a grounded surface before removing them from their containers.
●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 snugly against bare skin. The ground cord must be
connected to the banana plug connector on the grounding mat or workstation and t snugly into it.
●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, observe the following precautions:
●Cover the work surface with approved static-dissipative material. Provide a wrist strap connected to
the work surface and use 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.
10 Chapter 3 Routine care, SATA drive guidelines, and disassembly preparation

Recommended materials and equipment
The following grounding equipment is recommended to prevent electrostatic damage:
●Antistatic tape
●Antistatic smocks, aprons, or sleeve protectors
●Conductive bins and other assembly or soldering aids
●Conductive foam
●Conductive tabletop workstations with ground cords of one-megohm +/- 10% resistance
●Static-dissipative table or oor mats with hard ties 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-inch) 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.
Operating guidelines 11

●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 12 before cleaning the computer.
To clean the computer case, follow the procedures described below:
●To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab.
●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.
●For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed; alcohol will evaporate quickly
without leaving a residue.
●After cleaning, always wipe the unit with a clean, lint-free cloth.
●Occasionally clean the air vents on the computer. Lint and other foreign matter can block the vents and
limit the airow.
Cleaning the keyboard
Follow all safety precautions in General cleaning safety precautions on page 12 before cleaning the keyboard.
To clean the tops of the keys or the keyboard body, follow the procedures described in Cleaning the computer
case on page 12.
When cleaning debris from under the keys, review all rules in General cleaning safety precautions on page 12
before following these procedures:
CAUTION: Use safety glasses equipped with side shields before attempting to clean debris from under
the keys.
●Visible debris underneath or between the keys may be removed by vacuuming or shaking.
●Canned, pressurized air may be used to clean debris from under the keys. Caution should be used as too
much air pressure can dislodge lubricants applied under the wide keys.
