In this motherboard 3.3 and 5Volts regulator used Rt8206 was not being enable. Only 5 V_ alw2 being generated all input were ok instead enable, red round circle resistance was ok but still +3.3V_EN2 not going high finally reduce the resistance value to 10 ohms instead 39k job done.
Reason: as learnt slightly low resistance on enable point track or line so that enable signal not going high by reducing the value of resistance current also increased and signal maintained.
Dell A860 Vm9M 3.3 / 5 Volts are not Generated
