      There is a chance its a mosfet, (N-channel ) like product by UNIKC corporation or Niko-Semi. (by mark A5 or A1)
      From your pic near caps ( maybe with rate value 25v for 19v rails)

      Confirm it with remove it from the board, to see pad underneath. The package seem like PDFN 3x3P.
      hard to find datasheet from both corps.

      sometime we could dig more info from pics from seller on aliexpress or ebay

            Many thanks, but its the same ic u think, because the secaond part of marking is a little bit different.

            Hello no its not a classical Mainboard, its speciall designed and layouted device in medical services. (but its working like a laptop mainboard)

            There are no schematics or a pcb code because the Manufacturer doesnt support.

              How do you test MOSFET in laptops ?
              by Jane
              I tried to use this method:

              Testing an N-channel MOSFET:

              Step 1: Discharge the Gate (turn off the MOSFET)
              Place the black probe (COM) on the Source (S) and the red probe on the Drain (D). The multimeter should show no continuity (high resistance or "OL" – open line).
              Then, touch the black probe to the Source (S) and the red probe to the Gate (G). This discharges any stored charge in the Gate, turning the MOSFET off.

              Step 2: Charge the Gate (turn on the MOSFET)
              Now, place the red probe on the Gate (G) and the black probe on the

              burned mosfet wich has written on top "I6 GUE 8v1507"
              by Caly411
              Hi, Im having a similar problem with my Acer Nitro 5 AN517 52, took it to repair and they said that the problem was a burned mosfet wich has written on top "I6 GUE 8v1507".
              There is written PQB12 on the motherboard right next to it.
              Does anyone know if there is soemthing similar I can buy to replace it with?
              Seems impossible to find theidentical mosfet online.

              VGA MOSfet permanently shorted and loss of MOSfet pad
              by Nooy
              Hello everyone, I recently found this badcaps site and super Learn Electronics Repair youtube channel. And I wanted to learn how to troubleshoot power supplies and VGA cards and how to practice soldering, since I already have a properly defective piece of them. I am currently trying to solve two problems:

              I have a Gigabyte GV-RX460WF2OC-4GD type card. I managed to find the faulty MOSfet (AON6414A) on it, which I replaced. The card starts up, but after about half a minute, the MOSfet in the same position will be shorted again. Is it possible that the PWM controller driving the MOSfet...

              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 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...
