Flip the laptop over and slide the 2 tabs that are near the carry handle to the unlocked position. This will allow the metal cover on the underside of the laptop to hinge up and be removed.

With the laptop upside down and the carry handle facing you, you should see the battery on the left of the laptop. On the right, there is a silver case about 4 inches long and 2.5 inches wide. This is the hard drive caddy.

To remove /this/ part, carefully push the connecting cable towards the battery until it smoothly disconnects from the hard drive caddy. Remove the caddy from the laptop. Using a small phillips screwdriver, remove the 3 small screws which hold the top of the caddy on. Remove the top, and you will see the hard drive.

As a note - be sure you do not remove the gel lining. This is 99.9% of the hard drive's shock protection. When you remove the hard drive, the cable should come out of the caddy as well. Put the new cable on a new hard drive (HDD must be smaller than 65,536MB), put the new hard drive into the caddy with cable attached, make sure the cable assembly is fitted into the caddy slot, replace the caddy cover, replace the screws, replace the caddy into the laptop. Then, make sure you connect the cable from the laptop PC board to the caddy cable assembly. Replace cover, turn on computer, and set up your Operating System (if needed).
