Electrostatic Discharge (ESD) Precautions
ATTENTION
Follow these precautions to prevent ESD discharge.
• Transport the computer and replacement parts in static-safe containers such as
conductive tubes, bags, or boxes.
• Keep electrostatic-sensitive parts in their containers until they arrive at static-free
stations.
• Cover workstations with approved static-dissipating material. Use a wrist strap
connected to the work surface and properly grounded (earthed) tools and equipment.
• Keep work area free of nonconductive material, such as ordinary plastic assembly aids
and foam packing.
• Avoid touching pins, leads, or circuitry.
• Always handle the hard disk drive (HDD) by its metal frame and do not touch its
internal components.
• Always hold components with a printed circuit board (PCB) by its edges and lay it
with the assembly-side down.
Voltage Precautions
The computers contain line voltages. Disconnect all power to the computer before you install
or remove system components.
SHOCK HAZARD
Electrostatic Discharge (ESD) can damage static-sensitive devices or
microcircuitry. Observe proper packaging and grounding techniques to prevent
damage.
Disconnect power from the computer before removing components. Failure to
disconnect power could result in severe electrical shock and/or damage the
computer.
