HP Sleekbook 15-b003ee Power button flashing Continuously

[subroto]

Help me to recover a HP Sleekbook 15-b003ee.
MOBO ID: DA0U36MB6D0 REV: D
(Schematic is attached below.)

After pressing power button, both power button LED and power LED on MOBO start blinking in a long interval as 5 second.

I've flashed both EC and MAIN BIOS with known well one.
Have found MAINON, SUSON, VRON signal is becoming high along with the LED and immediately goes to LOW for 5 sec as the LED.
3.3V_ALW and 5V_ALW come after pressing power button.
3.3VLDO and 5VLDO is present.

I've also changed the KBC/SIO. But still have the same problem.
If anyone has solved the problem before then please give the case study. If not then please someone help me to find the problem.

Thanks in advance.
