HP TouchPad 844394-001 is the replacement touchpad listed for the HP EliteBook Folio 1040 G3 Notebook PC. It provides the laptop’s touchpad input surface as a service replacement part.
The guide shows the touchpad connected to the system board by a cable and secured with six Phillips screws. The cable is listed separately in a Cable Kit, so it is not identified as part of this touchpad entry.
The existing NFC antenna must be transferred to the replacement touchpad during servicing.
