I got a new D850GB mobo,look like FRONT PANEL conector spec have changed. According to INTEL , you use the J9D2 conenctor for POWER LED, RESET SWITH, POWER SWITCH , etc. Hovewer my board don't have any J9D2 connector, I got a J9B1 conector near of the CR2032 battery but the pin out is diferent. I only found Power Swith + HDD LED, anyone had this type of board. model number (AA A60568-900)
