16 Case Access
Follow these precautions to avoid electrostatic damage to your computer
components:
■ Avoid static-causing surfaces such as plastic and packing foam in your
work area.
■ Remove the parts from their antistatic bags only when you are ready to
use them. Do not lay parts on the outside of antistatic bags since only
the inside of the bag provides antistatic protection.
■ Always hold cards by their edges and their metal mounting brackets.
Avoid touching components on the cards and the edge connectors that
connect to expansion slots.
■ Never slide cards or other parts over any surface.
Opening the case
To work on the internal components of the computer, you must open the
case, which has two removable parts:
■ A chassis cover that surrounds the sides and top of the system
■ A front faceplate (bezel) that covers the front of the system
Because the components inside your computer are extremely sensitive to static
electricity, be sure to follow the precautions at the beginning of this chapter
for avoiding static electricity damage.
Warning Avoid exposure to dangerous electrical voltages and
moving parts, by turning off your computer and unplugging
the power cord and modem cable before removing the
computer cover.
Warning Avoid exposure to dangerous electrical voltages and
moving parts, by turning off your computer and unplugging
the power cord and modem cable (if installed) before
removing the chassis cover.
