Note: In the following two steps you will disengage the left and right sides of the bottom case and then pivot it forward to remove. [. . . ] (Figure 4) Important: Do not push on the rubber feet of the bottom case. Touch the computer's inside framework (a dull gray conductive composite material) to discharge any static electricity, as shown. (Figure 6) Important: To avoid electrostatic discharge damage, always ground yourself by touching the computer's framework before you touch any parts or install any components inside the computer. To avoid static electricity building back up in your body, do not walk around the room until you have completed your installation and closed the computer. Figure 6

Removing the Installed Hard Drive
1. With your fingers, carefully pry up the hard drive flex cable connector (Figure 7A) at its sides to disconnect it from the logic board. With a Torx T8 screwdriver, remove the two screws (Figure 8) that secure the hard drive to the mounting bracket and then gently remove the hard drive. Important: Do not pull on the flex cable or use the cable as a handle. Figure 8
Note: There are four rubber stoppers on the hard drive that fit over screws (two on each side). Remove any that may have fallen off or that remain in the holes in the mounting bracket inside the computer. Note: To help with alignment, the Torx T8 screwdriver can be inserted into the screws on the hard drive through the holes in the mounting bracket. Important: Verify that the bottom of the mounting bracket clears and seats behind a thin metal ridge located along the bottom of the battery compartment. Replace the screw (Figure 12C) in the top of the mounting bracket, being careful not to overtighten it. Connect the hard drive's flex cable connector (Figure 13) to the logic board. To attach the bottom case, align the notches on the right and left sides of the case, then press down slightly to secure the case. Check the alignment of the eight screw holes to make sure the bottom case is properly positioned. Important: Make sure that the seams between the bottom case and the frame are closed. Verify that the alignment tab on the underside of the bottom case (Figure 14A) has seated, and the case lies flat. (Figure 14) Note: The screws must go in straight and easily; if they do not, readjust the bottom case for proper alignment. Important: To avoid damaging the case, be careful that the screwdriver tip does not slip out of the screw head during tightening.
