Precision 7740 Palmrest Assembly

This genuine Dell OEM palmrest assembly is designed specifically for the Precision 7740 mobile workstation. It arrives new and includes the integrated touchpad, smart card reader, USH junction board with ribbon cable, and left and right mouse buttons. The part replaces a damaged or worn top case section on compatible Dell laptops.

Build Integration

Installation restores the primary pointing device, secure authentication reader, and physical click buttons in a single module. The assembly connects to the system board through the included USH junction board and ribbon cable, requiring no additional cabling. It fits the existing chassis mounting points for the Precision 7740, freeing the technician from sourcing separate touchpad or reader components.

Suitability

This unit suits repair technicians and owners restoring a Precision 7740 to factory specification with OEM parts. It is not for users of other Dell models or non-Dell laptops, nor for anyone needing a standalone touchpad, smart card reader, or button board without the surrounding palmrest frame.
