To remove the touch-pad assembly, follow these steps:

1. Remove the palmrest assembly.

2. Remove the hard-disk drive heat sink.

3. Remove touch-pad button screw H7.

This screw holds the touch-pad button board in place.

4. Disconnect the touch-pad cable from touch-pad button connector JP1.

This is a ZIF connector on the touch-pad board. See “ZIF Connectors”
found earlier in this chapter.

5. Remove the touch pad from the computer.

The touch pad and touch-pad board are held in place by a flange.

6. Remove the touch-pad button board from the touch-pad buttons.

The board is held in place by two tabs. Rotate the board from under the tabs.

7. Disconnect the touch-pad cable from connector JP2 on the touch-pad button

board.

This is a pressure-fit cable. Reconnect the cable before reinstalling the
board.
