    Lenovo Ideapad Flex5-14ALC05 PLTRST missing

    Hello i have this lenovo flex 5, in the power on sequence i have everithing but the last one PLTRST#, the resistance to grond turned off is in the mohms, qhen i turn on the laptop the resistance is going to 60ohms, so i think something is pulling down that line, cheking furter i see the APU is the one pulling down the signal to 60 ohm, is the APU bad? or i am missiong something else, i upload squematics and boardview.

    PD: the laptop power on but it dosent POST, i get all the voltaga lines and the signals but the PLTRST#

      Never measure resistance when motherboard is powered on-it may damage the multimeter.
