Caution: To prevent scratches or other cosmetic damage to the computer housing, use a soft cloth as a protective layer when removing and installing the external screws.

1. With the computer upright, remove the two identical 5.5-mm long shoulder screws from the right side of the computer.

Replacement Caution: When installing these top case screws, do not press on the area over the slot drive. The slot-drive bezel could be damaged with too much pressure.

2. Important: Notice the two screws at the left side of the computer. Although they can be removed, they exist for cosmetic purposes only and do not require removal. If they are removed, however, be sure to reinstall the two identical 3-mm long shoulder screws at the corner near the ports. Do not use longer screws.

3. At the back of the computer, remove the four #0 Phillips screws (two at each side) near the display hinge--

  • Two 12-mm long shoulder screws that are closest to the hinge
  • Two 8-mm long shoulder screws at the back corners of the computer

4. Turn over the computer, and on the outside of the bottom case, remove the three #0 Phillips screws:

Two 14-mm long screws near display hinge One 11-mm long at center of bottom case Replacement Caution: Do not put one of the longer screws in the center screw hole or it will damage the logic board.

Replacement Caution: When installing the three bottom case screws, install them in the order shown.

  1. Notice the long row of #0 Phillips screws at the front edge of the battery bay.
  2. Important: Remove only the four screws shown. Remove the 3-mm long identical screws as follows:

Starting at the corner closest to the battery connector, skip the first screw, then remove the second, fourth, seventh, and ninth screw.

Tip: To help remember the screw sequence, think of it as "2, 4, 7, 9 loosens the top case every time."

7. In the battery bay, remove the two 6-mm long identical screws that are on both outer sides of the battery connector. Do not remove the two screws that are closest to the battery connector.

8. In the battery bay, use a long-handled screwdriver to remove the three #00 Phillips screws at the inner edge of the battery bay near where the RAM slots are located:

  • Two identical 3-mm long screws
  • One longer 4.5-mm long screw at the corner of the battery bay nearest the battery connector

Because this is a recessed area, the screwdriver has to go in at an angle. Keep the screwdriver in line with the screw head as much as possible.

Replacement Caution: When installing these three screws, an incorrect installation could cause the reassembled computer to wobble in use. To prevent a wobble symptom, use light pressure to hold the top case onto the assembly when installing the screws.

  1. Open the display to a 90-degree angle or wider.
  2. Warning: Inserting a tool too far or performing this step too quickly could break some of the snaps that secure the top case. Be especially careful with the left front corner of the top case. Starting at the left corner and working in a counter-clockwise direction, use an access card tool to open the gap along the front of the top case, around the perimeter, and to the right side above the optical drive slot.

11. With the top and right side gap opened, tilt up—but do not remove—the right edge of the top case.This motion releases the remaining snaps between the top case and bottom case, and the slot-load bezel clips become loose as the top case is tilted up.

12. Without straining the trackpad cable, carefully lift up the top case so you can see where the folded trackpad flex cable attaches to the logic board.

14. Lift the top case up and away from the computer assembly.

15. Refer to the following notes to install the replacement top case, and reassemble and test the computer.

Replacement Note: The top case includes heatstaked keyboard, webbing, EMI shield, and attached trackpad cable.

Replacement Note: Before replacing the top case, make sure to connect the trackpad flex cable to the logic board.

Replacement Note: Install the right side of the top case first (near the disc bezel). Then starting from the right, secure the snaps by pressing along the outer edge of the top case in a clockwise direction around the front and left side of the top case.

Replacement Caution: When installing exterior and battery bay screws, apply light pressure to the top case to ensure that the top case fits to the bottom case without any gaps.

Replacement Note: Pinch the top case to the bottom case as you secure the screws.

Replacement Note: When installing the screws at the rear corners of the bottom case, insert an access card tool between the top case and the display to maintain light pressure as the screws are tightened.
