Lenovo Desktop PC Manuel D’Utilisation
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-protective
packaging
and
install
the
part
without
setting
it
down.
When
this
is
not
possible,
place
the
static-protective
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
cords
and
power
adapters
Use
only
the
power
cords
and
power
adapters
supplied
by
the
product
manufacturer.
The
power
cords
shall
be
safety
approved.
For
Germany,
it
shall
be
H05VV-F,
3G,
0.75
mm
2
,
or
better.
For
other
countries,
the
suitable
types
shall
be
used
accordingly.
Never
wrap
a
power
cord
around
a
power
adapter
or
other
object.
Doing
so
can
stress
the
cord
in
ways
that
can
cause
the
cord
to
fray,
crack,
or
crimp.
This
can
present
a
safety
hazard.
Always
route
power
cords
so
that
they
will
not
be
walked
on,
tripped
over,
or
pinched
by
objects.
Protect
power
cord
and
power
adapters
from
liquids.
For
instance,
do
not
leave
your
power
cord
or
power
adapter
near
sinks,
tubs,
toilets,
or
on
floors
that
are
cleaned
with
liquid
cleansers.
Liquids
can
cause
a
short
circuit,
particularly
if
the
power
cord
or
power
adapter
has
been
stressed
by
misuse.
Liquids
also
can
cause
gradual
corrosion
of
power
cord
terminals
and/or
the
connector
terminals
on
a
power
adapter,
which
can
eventually
result
in
overheating.
Always
connect
power
cords
and
signal
cables
in
the
correct
order
and
ensure
that
all
power
cord
connectors
are
securely
and
completely
plugged
into
receptacles.
