    Asus X570-P identifying potential missing SMD

    I am trying to identify a potential missing component from an Asus X570-P motherboard. I could not find a boardview for that exact motherboard, but I did find one for the X570-Pro here https://www.badcaps.net/forum/troubl...prime-x570-pro

    The component missing on my board I believe is a small 3 pin device above the Nuvoton Super IO. The X570-Pro uses a similar Nuvoton and there's a similar looking SMD just above it, though I'm going by somewhat low resolution images of both boards on the internet to try and confirm this.

    On the X570-Pro, I believe this is OQ762, and the pins go to H-SKTOCC#, O_DEEP_S5_R2, and Ground. But there's no part info. My guess is that perhaps this is just a simple transistor.

    Can't say I've sat down to do something like this before, so I wanted to see if my thought process was correct and if "find a transistor and solder it up to check" would be a good next step, or if I'd be better off asking for a schematic to try and confirm said part. I don't know if there's implied part types when they don't have info on the schematic like this.

    I have learned that the little three pins are called "SOT"s and it's probably a transistor. I tried just putting a larger transistor on and no dice, not sure if it's the wrong part or if something else is wrong with the board. Don't think I've got a chance without a schematic.

      ASUS STRIX G531GT MISSING PM_SLP_SUS#

      Hello guys i have ASUS laptop that power on but can't switch ons , i trying using power sequence and last missing PM_SLP_SUS# .
      here what i measure already:

      EC_RST# 3.3V
      SRTCRST# 3v
      +3VA_RTC 3V
      RTCRST# 3V
      ME_SusPwrDnAck 0V
      AC_PRESENT 3.3 V
      AC_IN_OC# 0V
      PS_ON 3,3V
      +3VA_DSW 3.3V
      DPWROK_EC /R 3.2V
      PM_BATLOW# 3.3V
      SM_INTRUDER# 2.8V
      PM_SLP_SUS# -----> MISSING VOLTAGE ( but sometime this voltage is present )

      THat is can confirm PCH relate issue...

      Asus Zenbook UX431DA / UM431D - Ryzen - missing PWM Fan Signal.
      by gurj1979
      Hey guys.

      Need help with this one.
      Fan not spinning due to missing PWN Fan signal.
      Also 5 seconds from powering up it freezes, unless in BIOS.
      But as soon as Windows starts to load, it will freeze.
      CPU is COLD / Room temp when it freezes.

      I've replaced the CPU, same problem.
      Replaced SIO/KBC IT8987e and reprogrammed - same problem.
      Replaced fan - same problem.
      Replaced flex cable from board to daughterboard (which has fan connector on it) - same problem.
      Checked the Thermal sensors around CPU and Board to the SIO/KBC and...
