Lenovo IdeaPad S9e -FR - Manual (Page 115)

– Avoid directly exposing your computer to the air from an appliance that can
produce negative ions.
– Keep your computer and peripherals as far as possible from such an appliance.
– Wherever possible, ground your computer to facilitate safe electrostatic
discharge.
Note:
Not all such appliances cause a significant electrostatic charge.
When you handle options or CRUs, or perform any work inside the computer, take
the following precautions to avoid static-electricity damage:
– Limit your movement. Movement can cause static electricity to build up around
you.
– Always handle components carefully. Handle adapters, memory modules, and
other circuit boards by the edges. Never touch exposed circuitry.
– Prevent others from touching components.
– 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.
– Whenever 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.
– Do not place the part on the computer cover or other metal surface.
