Electrostatic Discharge (ESD)

Static electricity, a normal and natural phenomenon, builds up on your body as you walk around. You experience an electrostatic discharge (ESD) when you touch an object and feel a shock or see a spark. ESD can cause damage to the internal components of your computer. To avoid ESD damage, read and follow all instructions.

 

 

 

Installing the Memory


  1. Turn your computer off by choosing Shut Down from the Special menu.
  2. Unplug all cables, except the power cord, from your computer. WARNING:If your internal modem is connected to a telephone line, disconnect the telephone line from the internal modem port before you open the access door. This prevents electric shock.
  3. Turn the computer so the screen is facing down See Figure 1.

  6. Touch the metal shield that is visible inside the recessed latch area before touching any components on the main logic board. This helps protect the computer from damage caused by electrostatic discharge. Important:To avoid electrostatic discharge, always ground yourself by touching the port access covers before you touch any parts or install any components inside the computer. To avoid static electricity building back up in your body, do not walk around the room until you have completed your installation and closed the computer. See Figure 4.
