    mosfet value for inspiron, vegas/turis 15341-1

    Hello. I was wondering if anyone has a spare board, to check the component number of a mosfet that burned out in my laptop. It is PQ4410. I cant tell if it should be a n-channel or p-channel mosfet, I get no voltage at gate when turning on the computer, so I dont know if someting else blew. If I bridge source to drain the computer does turn on. But I would like to replace the mosfet with the correct one.

    It is near the dc in connector. The voltage goes through a p channel mosfet, then goes into this burned mosfet .


    I have seached google photos for the board, but I cant find one with a close up to see the mosfet numbers. And there seems to be no leaked schematics for this board yet.

    I would solder N-channel for test. Won't hurt anything if you try it. Go for the highest amperage mosfet that you can find. If someone doesn't have exact board on hand for reference, it's gonna be a hit and miss. You could also try to determine the proper mosfet by checking which leg is supply voltage and which is load.

      as fuse says 1.1A u can use literraly any p-channel mosfet because 2A take anything

        just short without gate pin, for test purpose only. It seems to be pnp mosfet friend

            Its a P channel mosfet. Possible replacement is FDMC4435BZ. It should be same as two dc-in mosfets.

                Based on the picture, the original is a Alpfa & Omega AON7403, available from digikey.

                  I forgot I had posted. I put the computer aside. I have shorted it to make sure it works. Now I will order the correct part, that you guys have shown me. Thank you everyone for the replies.

                    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...

                    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...
