How to Open the Case of an HP Dec Z552

    • 1). Move your Z552 to a room with no carpet flooring. Make sure no cloth or material that creates static electricity is near the computer. Touch a grounded metal object to discharge any static electricity from your person.

    • 2). Locate the four screws holding the top panel on the back of the HP Z552.

    • 3). Use the Phillips screwdriver to unfasten the four screws and remove the top panel. This exposes the case contents.
