[操作疑難] Dell E6410 fail to power on

upgraded to win 10 from w7 and run smoothly. After upgrade software update patch and shutdown normally, the NB cannot bootup afterwards. The power button only light up for 1 seconds and turn off. No sound no fan and no display. Refer by google search: Have try to solve by disconnect AC power and battery, then keep pressing the power button over 1 minutes. However the problem still cannot fix. Any suggestion from C Hing?
