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 possible
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 telecommunication lines from the computer.
3 Remove the battery from the battery compartment.
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 static-sensitive component from its shipping
carton, do not remove the component from the antistatic packing
material until you are ready to install the component. Just before
unwrapping the antistatic packaging, be sure to discharge static
electricity from your body.
