The HP 840940-001 antenna kit is a replacement part for the display assembly of the HP ZBook Studio G3 Mobile Workstation. It contains the left and right antennas, identified by HP as the antenna components for this workstation’s display.
During service, the antenna cables are removed from their routing path along the display, and the antennas are detached from the display enclosure. This makes the kit relevant when replacing the display antennas as part of servicing the documented ZBook Studio G3 assembly.
The part is intended for the specific display assembly described in HP’s service guide. The guide identifies it as spare part 840940-001; it does not specify wireless standards, connector details or package contents beyond the left and right antennas.
