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. Also, disconnect any telephone or
telecommunication lines from the computer.
3. Remove the main battery from the battery com-
partment and, if necessary, the secondary battery
from the options 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.
P
rotecting 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, periodi-
cally 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 unwrap-
ping 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.
The following caution may appear throughout this docu-
ment to remind you of these precautions:
arms at desk level
computer positioned
directly in front of user
wrists relaxed and flat
CAUTION: See “Protecting Against Electrostatic
Discharge” in the safety instructions at the front of
this guide.
