D 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. To prevent damage to the computer, damage to a drive, or loss of information, observe these precautions:

If removal or installation instructions direct you to unplug the computer, unplug it after being properly grounded and before removing a cover.

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

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

Use nonmagnetic tools.

Before handling components, discharge static electricity by touching an unpainted metal surface of the component.

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

If you need more information about static electricity or assistance with component removal or installation, contact Customer Support.
