How to Open a Compaq Desktop
- 1). Turn off the computer and remove the power cord from the back of the unit. Turn the computer around so that the back is facing you.
- 2). Locate the screws on the back of the case. Most Compaq computers use two to four retaining screws on the case--one at each corner of the unit.
- 3). Remove the retaining screws and set them aside. Locate the case removal handle and flip it up to loosen and remove the case. Compaq desktop computers typically have this handle on the top of the unit near the middle of the case, while tower computers have the handle on the side of the case.
- 4). Slide the cover free of the case and set it aside. Perform the desired upgrades, then replace the case and power cord.
