Grounding methods

If removal or installation instructions direct you to unplug the computer, unplug it after being properly grounded and before removing a cover. Use one or both of the following grounding methods:

●Touch the exterior unpainted metal surface of a device that is connected to an electrical outlet by a grounding plug.

●Use a wrist strap connected by a ground cord to the computer chassis. Wrist straps are flexible grounding straps with a minimum of one megohm ±10 percent resistance in the ground cords. To provide proper ground, wear the strap snugly against your skin.

If you need more information about static electricity or assistance with component removal or installation, contact Customer Care.
