C 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 HP support.
