Opening the computer

1Shut down your computer by choosing Shut Down from the Special menu.

You can also press the Power key on the keyboard.

2Unplug all the cables except the power cord from your computer.

Leaving the power cord plugged in helps protect the computer from damage caused by electrostatic discharge.

IMPORTANT To avoid generating static electricity that may damage components, do not walk around the room until you have completed the installation of the expansion card or SIMM and closed the computer. Additionally, move the logic board as little as possible while it is outside the computer case.

3Place your thumbs on the two tabs at the top of the back panel, and press down.

4 Pulling gently, swing the panel down, and slip it out.

Remove the back panel.
