When Removing or Installing Memory Modules
Before removing or installing memory modules, perform the following steps in the sequence indicated.
NOTICE: The only time you should ever access the inside of your computer is when you are installing memory modules.
NOTICE: Wait 5 seconds after turning off the computer before disconnecting a peripheral device or removing a memory module to help prevent possi- ble damage to the system board.
1.Turn off your computer and any attached peripherals.
2.Disconnect your computer and peripherals from electrical outlets to reduce the potential for personal injury or shock. Also, disconnect any telephone or telecom- munication lines from the computer.

4.Ground yourself by touching the unpainted metal surface of the I/O panel on the back of the computer.
While you work, periodically touch the I/O panel to dissipate any static electricity that might harm internal components.
Protecting Against Electrostatic Discharge
Static electricity can harm electronic 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 a memory module. You can do so by touching an unpainted metal surface on the computer’s I/O panel.
As you continue to work inside the computer, periodically touch an I/O connector to remove any static charge your body may have accumulated.
You can also take the following steps to prevent damage from electrostatic discharge (ESD):
•When unpacking a
•When transporting a sensitive component, first place it in an antistatic container or packaging.
