Computer components are very sensitive to electrostatic discharge (ESD) which occurs when a computer component and another object such as a human hand come in contact and there is a rapid transfer of electrostatic charge due to ground potential differences between the two objects. ESD can seriously damage computer components if you touch a computer component with your hand and ESD occurs. Prevent ESD issues through proper grounding by using anti-static mats and wristbands when working on a computer.

    Place an anti-static mat on the desktop surface of a workbench. Plug the grounding connector attached to the mat into the wall socket. If the mat is equipped with only an alligator clip, proceed to the next step.

  2. 2

    Place the computer to be repaired on the anti-static mat. Unplug the power cord from the computer. Attach the alligator clip from the anti-static mat onto the metal chassis of the computer.

  3. 3

    Strap an anti-static wrist strap on your wrist. Attach the alligator clip on the wrist strap to the anti-static mat. You are now ready to work on the computer.
