Expansion memory is a precision electronic component that may be
fatally damaged by static electricity. Since the human body can carry
static electricity, it is important that you discharge yourself before
touching or installing any expansion memory modules. To discharge
your body’s static electricity, simply touch any metal close to you with
bare hands.
