IMPORTANT To avoid generating static electricity (from your body) that may
damage components, do not walk around the room until you have completed
the installation of the card and closed the computer. Additionally, move the
logic board as little as possible while it is outside the computer case.
1 Shut down your computer by choosing Shut Down from the Special menu.
You can also press the Power key (marked with a π) on the keyboard.
2 Unplug all the cables except the power cord from the computer (including the cable that
connects your keyboard to the computer).
Leaving the power cord plugged in helps protect the computer from
electrostatic discharge damage. You’ll unplug the power cord later.
