Static
electricity
prevention
Static
electricity,
although
harmless
to
you,
can
seriously
damage
computer
components
and
options.
Improper
handling
of
static-sensitive
parts
can
cause
damage
to
the
part.
When
you
unpack
an
option
or
CRU,
do
not
open
the
static-protective
package
containing
the
part
until
the
instructions
direct
you
to
install
it.
When
you
handle
options
or
CRUs,
or
perform
any
work
inside
the
computer,
take
the
following
precautions
to
avoid
static-electricity
damage:
v
Limit
your
movement.
Movement
can
cause
static
electricity
to
build
up
around
you.
v
Always
handle
components
carefully.
Handle
adapters,
memory
modules,
and
other
circuit
boards
by
the
edges.
Never
touch
exposed
circuitry.
v
Prevent
others
from
touching
components.
v
When
you
install
a
static-sensitive
option
or
CRU,
touch
the
static-protective
package
containing
the
part
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
static-sensitive
part
from
the
static-sensitive
packaging
and
install
the
part
without
setting
it
down.
When
this
is
not
possible,
place
the
static-sensitive
packaging
on
a
smooth,
level
surface
and
place
the
part
on
it.
v
Do
not
place
the
part
on
the
computer
cover
or
other
metal
surface.
Power
