HP 840791-BA1 is a Slovenian-layout replacement keyboard for compatible HP ProBook notebooks. It brings the keyboard and touchpad together in one notebook input component, supporting everyday typing and cursor control from the laptop’s palm-rest area.
The layout is specified as Slovenian, and the HP service guide identifies this part as an advanced keyboard with TouchPad for 14-inch products. The part number’s BA1 suffix corresponds to Slovenia in HP’s country-code table.
The listing names the HP ProBook 640 G2, 640 G3, 645 G2 and 645 G3 Notebook PCs as compatible models. This variant is suited to replacing the keyboard assembly on those listed notebooks when a Slovenian key layout is required.
