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.
