12 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 support.
