The HP 922749-271 is a backlit keyboard part for use in Romania, listed for the HP Elite x2 1012 G2 Tablet. It provides a keyboard input option for this tablet setup.
The backlit version is identified separately in HP’s parts guide from the non-backlit keyboard parts. The guide describes the keyboard as optional: it attaches to the tablet at its alignment post connectors and can be detached by pulling it away from the computer.
This part number identifies the Romanian regional version, so the country designation is part of the item’s identification.
