To remove a tilt-support foot, follow these steps:

1. Close the display assembly.

2. With the foot set to its fully retracted position, insert a small device (such as a scribe) into the bottom notch on the foot-retaining screw cover and gently lift out the cover partway. Lift on the sides of the cover, working around to the top, and then lift out the cover.

3. Remove the foot retaining screw.

The foot retaining screw also functions as a mounting screw for one of the display assembly hinges, which has a threaded hole for the screw. Therefore, the foot retaining screws cannot be reinstalled with the display assembly removed.

The foot-retaining screw cover can fit only one way in the foot. To reinstall the cover, make sure the tilt-support foot is in its fully retracted position. Then orient the cover with the notch toward the bottom of the computer and its mounting tab toward the top of the computer. Press in on the cover until it snaps into place.

Each of the hinge covers is held in place by three tabs that fit into slots on the display assembly base. The microphone is inside the right hinge cover. To remove the hinge covers, follow these steps:

1. Remove the display assembly from the computer.

2. Place the display assembly faceup on the work surface.

3. Rotate the display assembly base until the display assembly hinges are pointing upward at approximately a 45-degree angle.

4. To remove a hinge cover, press in on the front of the cover to release the hinge cover's front tab. Then rotate the cover in the direction of the arrow, and lift the cover away from the display assembly base.

To replace the hinge covers, set the display assembly base in the position shown, and reinsert the hinge cover into its original position, making sure that its two tab slots engage the tabs on the display assembly base. Then rotate the hinge cover opposite to the direction shown in Figure 4-18 until its front tab engages the tab slot in the display assembly base.

The display-assembly interface cable connects the system board, LCD panel, LCD inverter board, and LED board. The cable wraps around a bobbin. To remove the display-assembly interface cable, follow these steps:

1. Remove the display assembly.

2. Remove the display assembly bezel.

3. Remove the LCD panel.

4. Remove the left hinge cover.

5. Remove screws I1 and I2 securing the display-interface cable retaining bracket, then remove the bracket.

6. Disconnect the display-assembly interface cable from ZIF connector CN1 on the LCD inverter board.

7. Lift the display-assembly interface cable and bobbin out of the display assembly.

NOTE: Some computers have a display-assembly interface cable that detaches from the bobbin. If you have a cable with a permanently attached bobbin, stop here; otherwise, proceed to Step 8.

8. Look at the alignment marks on the display-assembly interface cable, and note the alignment of the cable to the bobbin. Then carefully detach the cable from the bobbin.

A double-sided adhesive strip attaches the cable to the bobbin (see Figure 4-20).

9. To reattach the display-assembly interface cable to the bobbin, align the marks on the cable with the notch in the shoulder of the bobbin, and then wrap the cable around the bobbin.

If you are installing a new cable, remove the protective cover from the adhesive strip on the new cable. Align the alignment marks on the cable with the notch in the shoulder of the bobbin, and then wrap the cable around the bobbin, making sure it stays between the shoulders of the bobbin. Place the cable and bobbin into the display assembly before attaching the EMI shield.
