    Help with mosfet knowledge

    Hi Folks

    Wonder if you can help

    my mosfet knowledge is not great

    so this is my question

    19v in

    1234 pins on mosfet 1= 19v
    5678 on mosfet 1 ==0v

    mosfter 2 12345678= 0v

    Now im guessing because 1 of the mosfet 1 legs has to have voltage
    Mosftet 2 is fine but no being turned on

    So is mosfet 1 faulty

      You must not oversimplify things like that. Even if it is "just" about a Mosfet. Sondirstbwe need to know about which particular circuit you're talking.

          Re: Help with mosfet knowledge

          pin 1-2-3 is source
          pin4 is gate
          pin 5-6-7-8 is drain

          Set your multi meter in ohms mode(200K or higher) and then meaure resistance between

          Source-gate
          Source-Drain
          Gate-drain

                  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                  ...

                  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...

                  Help identifying mosfet on Razer Blade RZ09 (CH570_MB_NT)
                  by redbaron1007
                  I have a Razer laptop (RZ09 MB# CH570_MB_NT) that has a shorted mosfet marked BND M03 E067 that I'm unable to find anywhere online. Does anyone either know what the part number is for this mosfet or have a schematic I can find it in?

                  Backstory on the whole thing the laptop was plugged into a lamp at a hotel. The lamp got unplugged while it was charging and now the system won't power on anymore. I found the caps around this mosfet shorted and when I injected voltage into the caps the mosfet got hot and my bench psu was pulling 5A. Pretty sure this is all that's wrong with the laptop...

                  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...
