Lenovo S9E Laptop User Manual


 
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.
