v Before you replace a new CRU, touch the static-protective package containing
the CRU to a metal expansion-slot cover or other unpainted metal surface on the
computer for at least two seconds. This reduces static electricity in the package
and your body.
v When possible, remove the new CRU from the static-protective packaging, and
install it directly in the computer without setting the CRU down. When this is
not possible, place the static-protective package that the CRU came in on a
smooth, level surface and place the CRU on it.
v Do not place the CRU on the computer cover or other metal surface.
