    Acer 5520 no cpu vcore

    I have this acer 5520 that is stuck in power on cycle.Its turn on than off after approximately 3 sec then on again.I mesure all power rails and find out that i dont have cpu vcore.I check voltage on vcc/vdd pin for MAX8774GTL (buck regulator) all good also ton and current ressistors are good and i have enable voltage.Anything else to check or is MAX877 dead? or maybe missing something.

      chek on the mini pci express slot , on pin 22 if once you press the on off button if you got PLTRST (since this command will activate CPU to wake up , this signal is sent by ICH once he receive rstrsm from KBC .
      so chek for PLT RST .
