Electrostatic Discharge (ESD)
Static electricity, a normal and natural phenomenon, builds up on your body
as you walk around.You experience an electrostatic discharge (ESD) when
you touch an object and feel a spark. ESD can cause damage to the
internal components of your computer.
To avoid ESD damage, read and follow all instructions. If a grounding wrist
strap is included with your replacement memory, refer to the instructions
included for how to ground and use the strap.
Opening the Computer
Warning: Always turn off your computer before opening it to avoid
