This particular laptop does not contain a hard drive-- yours will.

Identify the plastic tab located on the left side of the hard drive.

Grasp the tab, gently lift up, and slide the tab to the left to remove the hard drive from the laptop.

If you wish to replace your hard drive with another, the hard drive has a metal bracket screwed onto the sides of the casing. Unscrew the bracket from the old hard drive and screw it onto the new hard drive before inserting into the laptop.
