Precautionary Measures
Before you perform any procedure in this section, take a few moments to read the following caution for your personal safety and to prevent
damage to the system from ESD.
CAUTION: FOR YOUR PERSONAL SAFETY AND PROTECTION OF THE EQUIPMENT
Before you start to work on the system, perform the following steps in the sequence listed:
1. Turn off the computer and all peripherals.
2. Disconnect the computer and peripherals from their electrical outlets. Also, disconnect any telephone or telecommunication lines from
the computer. Doing so reduces the potential for personal injury or shock.
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 the electrical outlet 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 standby power LED 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
