How can I remove the hard drive from my HP EliteBook 820 G3 Notebook PC?

To remove the hard drive, start by turning off the computer, disconnecting all devices and power. Then, take off the bottom cover and battery, loosen the four captive screws securing the hard drive to the chassis, slide it away from the center of the system housing, lift it out, and if needed, separate the hard drive cover and bracket from the hard drive.
