Power on Lenovo G50-80 NM-A362 Ver 1.0 motherboard

[Phrang]

Hello,

I am a novice in laptop repair and i am going to repair my first laptop. Unfortunately i met with a compicated problem. My motherboard is Lenovo G50-80, NM-A362 Ver 1.0. I have a schematic with ver 0.4. The problem is that i cannot power on the motherboard though i am getting +3VALW and +5VALW at PJ303 and PJ306 respectively. Moreover, i am also getting 3.3V at the power button. As per the power sequence block, i should first get the signal DPWROK_EC which is not so. I could not also get the +3VS at pin 11 of IT8586E. Could some one guide me please?

...I have a schematic with ver 0.4...

Will be useful for people willing to help you in solving the problem to give them the link to the available schematic and /or boardview, right?
This time I'll do it for you, but keep in mind and do it yourself next time:
