Top Cover

HP Top Cover 821191-001 is a notebook spare part listed for HP EliteBook 850 G4 Notebook PC models. It serves as the computer’s top cover within the system’s case assembly.

HP’s service guide identifies this part number specifically for the EliteBook 850 G4. It lists a different top cover number for HP ZBook 15u G4 Mobile Workstation models, making the model distinction useful when identifying this component.

The guide treats the top cover as a separate service part that remains after the other spared components are removed. This is the cover component only; the source does not specify additional included parts.
