    Lenovo Yoga 2 13 LA-A921P - missing SYSON

    Hi all,

    I have a LA-A921P here on AC adapter
    • power LED on
    • button SW1 (power) pressed
    • the CPU gets warm
    • fan not spinning
    • no dead short found anywhere
    • +5VALW/+3VALW present
    • DDR_VTT_PG_CTRL is 5V
    • SYSON is 0V
    the +0.675VSP and +1.35VP is missing, assuming because of missing SYSON signal
    SYSON is not shoted to ground
    the SYSON is generated by U51 hope it's not it

    Is there anything i can test?

    Many thanks,

    -jp
