Before you open the computer cover, perform the following steps in the sequence indicated.
1. Perform an orderly computer shutdown using the operating system menu.
2. Turn off your computer and all devices.
3. Ground yourself by touching an unpainted metal surface at the back of the computer before touching anything inside your computer.
While you work, periodically touch an unpainted metal surface on the computer to dissipate any static electricity that might harm internal components.
4. Disconnect any devices connected to the computer, including the monitor, from their electrical outlets to reduce the potential for personal injury or
shock. Also, disconnect any telephone or telecommunication lines from the computer.
5. Disconnect the power cable from your computer, and then press the power button to ground the system board.
In addition, take note of these safety guidelines when appropriate:
l When you disconnect a cable, pull on its connector, not on the cable itself. As you pull connectors apart, keep them evenly aligned to avoid bending any
pins. Also, before you connect a cable, make sure that both connectors are correctly oriented and aligned.
l Handle components and cards with care. Don't touch the components on a card. Hold a card by its edges or by its metal bracket.
Protecting Against Electrostatic Discharge
To prevent static damage, discharge static electricity from your body before you touch anything inside your computer and periodically while you work inside the
computer. You can do so by touching an unpainted metal surface on the back of the computer.
You can also take the following steps to prevent static damage:
l Do not remove items from their antistatic packing material until you are ready to install them in your computer. Just before unwrapping the antistatic
packaging, be sure to discharge static electricity from your body.
l When transporting a sensitive component, first place it in an antistatic container or packaging.
