- 1). Turn your laptop off, unplug it and disconnect the battery to help prevent a sudden power spike from damaging your laptop or hard drive.
- 2). Find the hard drive upgrade bay on the underside of your laptop. Generally, the upgrade bay will be secured by four screws in a rectangular pattern roughly the size of a hard drive. Unscrew the hard drive tray and slide it out of the upgrade bay.
- 3). Remove the old hard drive from the tray by unscrewing the four screws that hold it in. Reserve the screws.
- 4). Place the new hard drive into the tray, ensuring that the screw holes in the tray line up with those on the drive itself. Screw the drive into the tray.
- 5). Slide the drive tray back into the laptop's upgrade bay using gentle, even pressure. Once the tray is inserted completely, replace and tighten the screws.
- 6). Replace the laptop's battery and connect the laptop to AC power. Turn the laptop on. The new hard drive should be recognized and spin up automatically.
