Schematic for the button board of Quanta project FF4, filed under DA0FF4MB6E1, revision R1C final, in PDF format. This small sub-board usually carries the power switch and may carry status LEDs, and its cable runs to the motherboard. The diagram helps check the switch and connector pinout when a laptop will not respond to the power button. Confirm the revision on the sub-board, and for the power-on signal path beyond the connector consult the motherboard schematic and boardview.
