Dell Precision 340: When Using Your Computer (continued) Protecting Against Electrostatic Discharge Ergonomic Computing Habits

When Using Your Computer (continued)

• Handle components and cards with care. Do not touch the components or contacts on a

card. Hold a card by its edges or by its metal mounting bracket. Hold a component such

as a microprocessor chip by its edges, not by its pins.

CAUTION: There is a danger of a new battery exploding if it is incorrectly installed.

Replace the battery only with the same or equivalent type recommended by the

manufacturer. Do not dispose of the battery along with household waste. Contact

your local waste disposal agency for the address of the nearest battery deposit site.

Protecting Against Electrostatic Discharge

Static electricity can harm delicate components inside your computer. To prevent static

damage, discharge static electricity from your body before you touch any of your computer’s

electronic components, such as the microprocessor. You can do so by touching an unpainted

metal surface on the computer chassis.

As you continue to work inside the computer, periodically touch an unpainted metal surface to

remove any static charge your body may have accumulated.

You can also take the following steps to prevent damage from electrostatic discharge (ESD):

• Do not remove components from their antistatic packing material until you are ready to

install the component in your computer. Just before unwrapping the antistatic packaging,

discharge static electricity from your body.

• When transporting an electrostatic sensitive component, first place it in an antistatic

container or packaging.

• Handle all electrostatic sensitive components in a static-safe area. If possible, use

antistatic floor pads and workbench pads
