(often labeled as GPC56 LA-J494P) is a Compal OEM motherboard used in HP Envy x360 15-ED
When working with I-LAJ494P schematics in power supplies, remember that the primary side carries lethal DC voltages (300V+). Always use an isolation transformer when probing the circuit with an oscilloscope and ensure the large electrolytic capacitors are fully discharged before soldering.
