Power Supply To access some of the components on the system board, you may need to rotate the system power supply out of the way. CAUTION: Before you perform this procedure, see "Safety First- For You and Your Computer." 1 Turn off the computer and peripherals, disconnect them from their electrical outlets, wait at least 5 seconds, and then remove the computer cover. 2 Ensure that the AC power cable is disconnected from the AC power receptacle on the back of the power supply. See "Rotating the Power Supply (Mini Tower Chassis)" or "Rotating the Power Supply (Desktop Chassis)." 3 Free the power supply from the securing tab by pressing the tab labeled "RELEASE." Then rotate the power supply upward until it locks in its extended position. Instal ling Upgr ades 61
