Opening the Computer

1.Shut down the computer.

Warning: Always shut down the computer before opening it to avoid damaging its internal components or the components you are installing. Do not open the computer or attempt to install items inside it while it is on.

2.Wait 5 to 10 minutes to allow the computer’s internal components to cool.

Warning: After you shut down the system, the internal components can be very hot. You must let the computer cool down before continuing.

3.Unplug all external cables from the computer except the power cord.

4.Touch the metal PCI access covers on the back of the computer to discharge any static electricity from your body. (Figure 2)

Important: Always discharge static before you touch any parts or install any components inside the computer. To avoid generating static electricity, do not walk around the room until you have finished working and closed the computer.
