HP 929904-BA1 is the Slovenian top-cover and keyboard spare part listed for the HP 255 G6 Notebook PC. It provides the built-in keyboard and upper palm-rest assembly as a replacement part for a matching notebook configuration.
This version belongs to the asteroid silver, non-backlit 929904 family. The regional suffix matters: HP identifies -BA1 for Slovenia, distinguishing it from keyboard variants intended for other country or language layouts.
The service guide describes the kit as including the keyboard and its cable, with a backlight cable included if equipped. The top-cover/keyboard kits in this parts section also include a TouchPad.
