Sometimes you'll need to remove the cover on your HP Compaq desktop computer for the purpose of replacing a part, adding hardware or just for dusting. Each brand of computer has a different case and it can be puzzling to remove the cover. Start your computer maintenance by clearing a workspace on a clean tabletop. It is best to work over a floor without carpeting to avoid static electricity discharges.

Turn off the HP Compaq and unplug the power supply from the wall. Remove all wires from the computer tower and lay the tower on its side on a tabletop. The side with all the hardware connections (for example, USB ports) should be down against the tabletop.
Remove the case screw, which is the only screw attached to the back of the cover. If the screw is too tight to remove with your fingers, then remove it using a flat-bladed screwdriver. Place the screw in a cup so it does not get misplaced.
Place you fingers in the indentation on the side panel and slide the whole panel towards the back of the tower, which is the end with the fan vents. It may take some strength to loosen the side panel. Once it is loose, lift the side panel upward and back to remove it from the framework.
Stand the HP Compaq desktop tower upright and locate the green release button in the upper right corner inside the computer. Press this green button to release the upper tabs on the front panel. If the panel is secured tightly to the frame, the front panel may pop out of place.
Place one hand in front of the cover to prevent it from falling. Find the black tabs attaching the faceplate to the frame, which are halfway down the front past the green drive-by tabs. Push these tabs through the frame and remove the front cover. All components of the HP Compaq computer are now accessible.
Tips and warnings
- Touch the metal frame of the computer before touching any of the computer components. This discharges any collected static electricity and prevents you from accidental zapping the hard drive or motherboard, which would ruin these pieces of hardware.
- Do not break any of the plastic tabs holding the front cover in place. These are the only things holding the front cover in place and cannot be replaced. If they are broken, the entire front cover will have to be replaced.
