3. If you are disconnecting a peripheral from the computer or are removing a component from the system board, wait 10 to 20 seconds
after disconnecting the computer from AC power before disconnecting the peripheral or removing the component to avoid possible
damage to the system board.
4. Wear a wrist grounding strap, and clip it to an unpainted metal surface, such as the padlock loop on the back of the chassis. If a wrist
grounding strap is not available, touch any unpainted metal surface on the back of the computer or on the computer chassis, such as
the power supply, to discharge any static charge from your body before touching anything inside the computer. While you work,
periodically touch an unpainted metal surface on the computer chassis to dissipate any static electricity that might harm internal
components. Also avoid touching components or contacts on a card and avoid touching pins on a chip.
5. Verify that the auxiliary power indicator on the system board is not on. If it is on, you may need to wait 10 to 30 seconds for it to go out
(see Item 13 on Figure 17 ).
