■ Expansion memory is a precision electronic component that may be
fatally damaged by static electricity. Since the human body has slight
static electricity, be sure to discharge static electricity from your body
before installing an expansion memory module. To discharge your
body's static electricity, simply touch any metal close to you with bare
hands.
