HP L72709-001 touchpad is a replacement service part for the HP Pavilion Gaming 15 Laptop PC. It provides the laptop’s built-in touch input and is listed by HP under this exact spare part number.
The touchpad connects to the system board through a cable and ZIF connector. Its bracket and the touchpad itself are secured with screws, so the part is fitted inside the computer during service.
The touchpad cable is not included in the kit. HP lists that cable separately as L72707-001, so this item is the touchpad component only.
