16 Electrostatic Discharge

Preventing electrostatic discharge

Electrostatic discharge is the release of static electricity when two objects come into contact—for

example, the shock you receive when you walk across the carpet and touch a metal door knob.

A discharge of static electricity from fingers or other electrostatic conductors may damage electronic

components. Before handling electrostatic-sensitive components, discharge static electricity by using

one of the methods described in this chapter.

Handling drives

CAUTION To prevent damage to the computer, damage to a drive, or loss of information,

observe these precautions:

Before handling the drive, discharge static electricity by touching the unpainted metal surface

of the drive.

Do not touch the drive connector pins on the drive or on the computer.

Handling internal components

For best results when handling internal components, have everything needed for the installation

within reach so that you do not need to leave the area after beginning the procedure. If you must

leave the area during the procedure, remember to reground yourself before resuming the procedure.

CAUTION To prevent damage to the computer when you are removing or installing internal

components, observe these precautions:

Keep components in their electrostatic-safe containers until you are ready to install them.

Use nonmagnetic tools.

Before touching an electronic component, discharge static electricity by using one of the

grounding methods described in this chapter.

Avoid touching pins, leads, and circuitry. Handle electronic components as little as possible.

If you remove a component, place it in an electrostatic-safe container.
