Opening the computer
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 expansion 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 ) on the keyboard.
2Unplug 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.)
3Place your thumbs on the two tabs at the top of the computer’s back panel, and press down.
Leave the power cord plugged in for now. You’ll unplug it later.
