WARNING

Hewlett-Packard does not support power supply upgrades. This information is provided to help you replace a defective

power supply unit. For your safety, only replace with a power supply provided by HP support services.

To avoid electrical shock, do not open the power supply. There are no user-serviceable parts inside.

For your safety, disconnect the power cord and all external cables.

Replacing the Side Panel” on page 12).

2 Remove the four screws from the rear of the PC.

3 Disconnect all power cables from installed drives and from the system board.

4 Lift the power supply unit out of the PC.

6 Reconnect all the power cables to the drives and the system board.

7 Replace the PC’s side panel (refer to “Removing and Replacing the Side Panel” on page 12).
