HP 902368-001 audio board is a service replacement component for the HP x2 Detachable PC and HP x2 210 G2 Detachable PC. HP’s service guide identifies this exact part number as the audio board, so it is distinct from the separate bracket and cable listed alongside it.
The board connects to its cable through a ZIF connector and is removed from the display assembly during service. It is intended for repair work on the documented HP x2 tablet families where the audio board needs replacement.
The bracket and cable have separate part numbers, so this listing identifies the board itself; the source does not confirm package contents.
