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 telecommunication lines from the computer.
3
Remove the main battery from the battery compartment and, if
necessary, the secondary battery from the modular 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.
The following notice may appear throughout your Dell documentation to
remind you of these precautions:
