1 Disconnect the AC power cable from the back of the power supply.
2 Disconnect the DC power cables from the system board and the
drives.
Note the routing of the DC power cables underneath the clips in the
computer as you remove them from the system board and drives. It is
important to route these cables properly when you replace them to
prevent them from being pinched or crimped.
3 On the small desktop computer, remove the expansion-card cage and
remove the power cables from the side of the hard drive. To remove
the power cables, use the cables as leverage and pull away from the
clips while simultaneously pulling on the metal clips with your fingers.
4 On the small mini-tower computer, remove the two screws that attach
the power supply to the rear wall.
5 Press the release button. On the small desktop computer, press down
on the handle, which in turn presses on the release button.
6 Slide the power supply toward the front of the computer
approximately 1 inch.
