HP 836621-BA1 is a Slovenian-layout replacement keyboard listed by HP for EliteBook 850 G4 notebook models. Its regional suffix identifies the Slovenian version, making it a suitable part reference when replacing that keyboard variant.
This model is non-backlit, so its keys do not have keyboard illumination. HP’s service procedure also shows a separate connection for the pointing stick cable, reflecting the keyboard’s pointing-stick configuration.
The part is intended for use in the named EliteBook family; the service guide does not establish compatibility with other models.
