SPS-TOUCHPAD 15

HP Touchpad M21999-001 is a replacement touchpad component for a compatible HP computer. It provides the touch-sensitive pointing surface used to control the on-screen pointer and interact with the computer without a separate mouse.

The service guide identifies this exact part number as the touchpad spare. It connects to the system board through a cable and ZIF connector, allowing it to integrate with the computer’s internal controls. The touchpad cable is listed separately as part of Cable Kit M21713-001, so it is not identified as part of this part number.

For service installation, HP specifies five M2.0 × 2.0 screws and one M1.6 × 2.0 screw to secure the touchpad. The part is intended for repair or replacement in the computer configurations that use M21999-001.
