Preventing static electricity 
discharge
The components inside your notebook are extremely sensitive to static 
electricity, also known as electrostatic discharge (ESD).
Before installing memory or replacing the hard drive, follow these guidelines:
■Turn off your notebook.
■Wear a grounding wrist strap (available at most electronics stores) and 
attach it to a bare metal part of your workbench or other grounded 
connection.
■Touch a bare metal surface on your workbench or other grounded object.
■Unplug the power cord and the modem and network cables.
■Remove the battery. For more information, see “Changing batteries” on 
page 147.
■Disconnect all peripheral devices and remove any PC Cards.
WarningESD can permanently damage electrostatic 
discharge-sensitive components in your notebook. Prevent 
ESD damage by following ESD guidelines every time you 
install memory or replace the hard drive.
WarningTo avoid exposure to dangerous electrical voltages and 
moving parts, turn off your notebook and unplug the power 
cord and modem and network cables before opening the 
case.
WarningTo prevent risk of electric shock, do not insert any object 
into the vent holes of your notebook.

Preventing static electricity discharge

Before working with computer components, follow these guidelines:
■Avoid static-causing surfaces such as carpeted floors, plastic, and packing 
foam.
■Remove components from their antistatic bags only when you are ready 
to use them. Do not lay components on the outside of antistatic bags 
because only the inside of the bags provide electrostatic protection.
■Always hold components by their edges. Avoid touching the edge 
connectors. Never slide components over any surface.
