When Removing or Installing Memory
Modules
Before removing or installing memory modules, perform
the following steps in the sequence indicated.
NOTE: The only time you should ever access the inside
of your computer is when you are installing memory
modules.
1. Turn off your computer and any attached
peripherals.
2. Disconnect your computer and peripherals from
AC power to reduce the potential for personal
injury or shock.
3. Remove the main battery from the main-battery
compartment. If necessary, remove the optional
second battery from the options bay.
4. Open the input/output (I/O) panel door on the
back of your computer, and ground yourself by
touching an I/O connector.
While you work, periodically touch an I/O connector
to dissipate any static electricity that might harm
internal components.
Additional Safety Guidelines
In addition, take note of these safety guidelines when
appropriate:
• Do not attempt to service the computer yourself.
Always follow installation instructions closely.
• When you disconnect a cable, pull on its connector
or on its strain-relief loop, not on the cable itself. As
you pull connectors apart, keep them evenly aligned
to avoid bending any connector pins. Also, before
you connect a cable, make sure both connectors are
correctly oriented and aligned.
• Handle components with care. Hold a component
such as a memory module by its edges, not by
its pins.
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 one of the unpainted
metal connectors on the computer’s I/O panel.
As you continue to work inside the computer, periodi-
cally touch an I/O connector to remove any static charge
your body may have accumulated.
In addition to the preceding precautions, you can also
take the following steps to prevent damage from electro-
static 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 elec-
tricity 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.
The following caution appears throughout this document
to remind you of these precautions:
CAUTION: See “Protecting Against Electrostatic
Discharge” in the safety instructions at the front of
this guide.
