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.

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 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.
