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 o ff the comp uter befor e disconnect ing
a peripheral device or removing a memory module to help prevent poss i-
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.
3. Remove the main batter y from the Battery Bay and, if necessary, the secondary
battery from the media bay.
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.
•When transporting a sensitive component, first place it in an antistatic container
or packaging.
•Handle all sensitive components in a static-safe area. If possible, use antistatic
floor pads and workbench pads.
