Upgrading Your System Removing the Power Supply Removing the Power Supply 1. Position the workstation on its side so the power supply label is facing you. It is best to use a cushioned surface to protect the exterior of the system from damage. 2. Position the conductive sheeting so that an inch of one edge is under the workstation and the rest is ﬂat against the work area to lay system components on after you remove them. Also ensure that your static-grounding strap is securely attached to your wrist and to bare metal on the workstation. Figure 2-7.

Alternately loosen the two T-15 Torx screws from the corners of the power supply as shown above. 14 Chapter 2
