      Asus X712EA 3 volts after the first mosfet
      by AppleLover123
      Hey guys,

      i have a asus motherboard here and as the title says after the first mosfet (in the picture) there is nothing more than 3.15v.
      I injected 19v and max. 1 amp at the charging port and there is not voltage drop or smth. It's just taking 19v and 1 milliamp.
      Then i tried to inject 19v and max 1amp after the current sensor and there it first takes 19v and 4 milliamps and after 2 seconds it is taking nothing (no current).
      I measured on the coils on board everything seems fine. Also the main power rail is not shorted (infinite resistance).
      Now i thought something...

      Asus GA502D keeps blowing mosfet
      by Scotchmist
      I have an Asus GA502D, it had a blown mosfet which I replaced and the laptop booted into windows, a few mins later it shut off, the same mosfet was blown. I thought maybe just a bad mosfet but same thing happened again, a few mins in windows and shuts off.

      I have removed the mosfet and can run the laptop no problem

      The MOSFET is FDPC5018SG

      Can anyone point me in the direction of what could be the cause of this, could it be the controller rt3663bc?

      Thanks

      ASUS ROG Zephyrus GPU Mosfet repeat failure
      by MicroSMD Lab
      The board number is GU502DU. I repaired this a couple weeks ago and it came back with the same issue, same mosfet failed (PQH9201). I'm hoping that the GPU was spared this time.
      I used the same replacement part (purchased from Mouser) and I'm certain the soldering was done properly since it took just as much effort to remove as before. What could cause this same mosfet to fail? I'm thinking if it was unsuitable then the others would fail too. I looked for similar failures on YTube and the mosfet was replaced with AOE6930 in one instance and AOE6932 in the other but it's possible that the...

      Odd MOSFET only on some ASUS x99/x299/z370 motherboards..
      by Timp74
      Hi All,
      Could anyone comment on the purpose of the MOSFET circled in red in the attached photo of an ASUS ROG X299 Extreme VRM?

      I'm trying to fix an ASUS motherboard(WS x299 SAGE) with a similar VRM where this MOSFET has burnt out along with one of the IR3555m driver chips. From looking at photos of motherboard VRMs on the internet, it seems only some ASUS motherboards have a MOSFET like this. Although I've seen some photos of ASUS z370 boards where it's not populated. The MOSFET is usually a NTMFS4C06N. It has its drain connected to the output of the Vcore VRM, and on...
