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 the electrical outlets to reduce
the potential for personal injury or shock. Also, disconnect any telephone or
telecommunication lines from the computer.
3. Remove the main battery from the MegaBay and, if necessary, the second
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.
