When installing: When you attach the palm rest, do as follows:
- Attach the fingerprint reader connector firmly to the system board.
- Attach the palm rest so that the two projections of the palm rest (a) firmly fit into the guide holes of the keyboard bezel as shown in this figure.
- Push the front side of the palm rest until it clicks into place.
- Close the LCD cover and turn the computer over. Then fasten the four screws to secure the palm rest.
