The HP Pavilion dv7 notebook is an entertainment notebook computer that has the hardware capability to function as a desktop PC. It comes standard with one hard drive but has an additional bay for a second drive, which means you can upgrade when you purchase your computer or later on. If you experience a hard drive failure or decide that it's time to upgrade to a larger hard drive, you can access the drive bays by removing the back cover from the notebook.
Power off the HP Pavilion dv7 notebook and disconnect any cables and external devices from the computer.
Lift the notebook up and place it face down on a flat work area. Turn the computer so that you are looking at the back edge. The battery is located near the bottom of the notebook, in the middle.
Push the battery-release latch to the right and hold it to disengage the battery from the notebook. The latch is located above the upper left edge of the battery. Lift and remove the battery out of the compartment with your free hand.
Remove the two screws in the back notebook cover, directly above the battery bay, and the one screw in the middle of the back cover using a Phillips-head screwdriver. Rotate the notebook 180 degrees.
Remove the screw on the left and right edge of the back cover using the Phillips screwdriver. Lift the back cover off the notebook and put it aside. Look for the primary hard drive in the lower right corner of the exposed unit. The secondary hard drive, if one is installed, is located in the lower-left corner of the notebook.
Disconnect the small, plastic drive connector from the notebook. The connector cable extends from the right side of the hard drive and is about 1 inch wide.
Remove the screw in each corner of the hard drive using the Phillips screwdriver. The drive is held in placed by four screws. Lift and remove the hard drive bracket from the notebook.
Pull the rubber bumper in each corner of the bracket free of the bracket.
Disconnect the interposer from the right side of the hard drive. The interposer is on the left side of the drive connector cable and is a 3-inch wide plastic piece that plugs directly into the hard drive.
Remove the two screws on the long side of the drive using your Phillips screwdriver. You'll find two screws on each side.
Slide the hard drive out of the retaining bracket. Repeat this procedure to remove the second hard drive, if one is installed in your Pavilion notebook.
Wear a grounding strap when working inside your laptop to prevent damaging the internal components by accidental discharge of static electricity.
